1. INTRODUCTION

Pioneering studies on spontaneous radioactive processeshave considered alpha decay and fission as completely differ-ent phenomena from each other as far as the internal nuclearstructure is concerned. However, during the 80’s, this conceptwas changed after the first reports on the possible occurrenceof a very asymmetric mass splitting of heavy nuclei [1–3],and the subsequent discovery of a new spontaneous decayprocess, namely, the cluster radioactivity [4, 5]. Theoreticalpredictions of the half lives for this new nuclear radioac-tive decay mode have been made, on the one hand, in theframework of the fragmentation theory [6–8] based on thetwo-center shell model [9, 10]. The idea has been limited tothe cold rearrangements of a large number of nucleons in theground state of the parent nucleus. On the other hand, thecluster radioactivity process has been interpreted differentlyin terms of a clustering preformation followed by fragmentemission. In these treatments, the emission of light clusterssuch as 14C has been interpreted in terms of “cluster-likedecay” [11–13], while for heavier fragment emission modes(24Ne, 30Mg, 34Si, and 48Ca) the interpretation has followedthe“fission-like approach.” A systematic investigation ofthe new decay modes based on the analytical superasym-metric fission model (ASAFM) by Poenaru et al. [14] re-vealed a number of nuclides with Z > 40 which are foundto be metastable with respect to heavy-ion emission modes.The ASAFM, which takes into account even–odd effects, wassubsequently updated, to also include superheavy nuclei andnuclei far off the beta-stability valley [15].

236

In the early 90’s, a new fission process was observed forthe first time as resulting from the emission of two fragmentsof comparable masses in their “cold” ground state; therefore,with no neutron emission—the so-called cold fission process[16]. The occurrence of cold fission is also related to shelleffects on the barrier, and the total kinetic energy of the finalfragments practically exhausts the Q value for the process.Several theoretical descriptions have appeared to treat thesethree processes (alpha decay, cluster radioactivity, and coldfission) within the same theoretical framework, as a manifes-tation of structure effects such as the shell corrections, andthe pairing and symmetry energy effects [17–26]. Duringthis decade or so, nuclear cold fission and cluster radioactiv-ity processes have been explored intensively from both theexperimental and theoretical point of views [17–19, 27–30].The newest available cold fission data are from the decayof 230Th [31], 236,238,240,242,244Pu [31–33], 248Cm [28], 252Cf[34–36], and 233,234U [31, 37] isotopes.

Nowadays special attention has been dedicated to newnuclear properties that can be deduced from the processesof proton radioactivity and alpha decay observed in theregion of proton-rich nuclei. Indeed, the competition be-tween spontaneous proton emission and alpha decay [38]is a promising tool for the analysis of possible peculiar-ities in the structure of these proton-rich nuclei [38–51],and also of great interest to the rapid proton-capture astro-physical nucleosynthesis, namely the rp process. At present,there are few calculations, based mainly on Hartree–Fock

[52], Hartree–Fock–Bogoliubov [53], and effective liq-uid drop theory [54], to describe the nuclear structureand/or to calculate the half-life for the proton radioactivityprocess.

The effective liquid drop model (ELDM), formerly de-veloped to describe the alpha decay and cluster radioactivityprocesses in a unified framework [13, 26], has been extendedto include the cold fission process, and also to discuss theeffect of different inertia coefficients on the calculated halflives and product mass yield distributions. It has been al-ready shown that the half-life results calculated using such amodel depend strongly on the prescription employed to de-scribe the changing of the mass asymmetry parameter duringthe scission process. However, we have demonstrated that,by redefining appropriately the values for the model param-eters, we can reach good agreement with the existing data[21, 23, 24]. This agreement has been observed for the alphadecay [22] and cluster radioactivity [23] processes, both forthe earlier data [13, 26] and the most recent data, where newregions of daughter nuclei around the double-magic 100Sn50

and 132Sn82 nuclei are expected to occur [21, 26, 55, 56]. Infact, we have used our model to predict some new regions ofinstability which, through cluster emission, lead to proton-rich valleys around 100Sn50 [21]. Results have shown that,besides the probable 12C cluster radioactivity, other emittednuclei such as 14N and 16O can also lead to double-magic-shell daughter nuclei [21].

In the limit of smallest fragment emission, our modelcan deal also with the proton emission phenomenon, givingpredicted half-life values for several proton emitter nuclei inexcellent agreement with the recent data [54]. Therefore, wecan state that the present ELDM, although semiclassical incharacter, has shown to be a valuable tool in predicting thehalf lives for different nuclear decay processes in a unifiedtheoretical framework.

The aim of this work is to update the half-life estimationsfor proton emission, alpha decay, cluster radioactivity, andspontaneous cold fission processes within the ELDM usingthe most recent atomic mass data tables by Audi et al. [57]and Moller et al. [58] as input data. In the next sections, wedetail the most relevant aspect of the model we are using.The results and comments are presented in the last section.All decay cases within the limits of measurable half lives aredisplayed in a table.

Coulomb and surface potential energies required to calcu-late the total potential barrier. Gamow’s penetrability factor[59] is calculated by considering (i) Werner-Wheeler’s in-ertia coefficient [60] and (ii) the effective inertia coefficient[26].

During the molecular phase of the process, the geometri-cal configuration of the deformed system is approximated bytwo intersecting spheres of different radii. For the completespecification of this configuration, we need four independentcoordinates, disregarding the location of the center-of-massof the system. Figure A shows a sketch of a typical configu-ration, where the choice for the coordinates are specified:the radii of each spherical segment, R1 and R2; the heightof the largest spherical segment, ξ ; and the distance betweentheir geometric centers, ζ . At the end of the molecular phase,the system reaches a limiting configuration of two spherical,tangent fragments with radii R1 and R2, respectively, for theemitted fragment and daughter nucleus.

Three constraints have been introduced to reduce thespherical four-dimensional problem to the equivalent one-dimensional one. To preserve the adopted shape parametriza-tion for the deformed nuclear system during the molecularphase, i.e., to keep the spherical segments in contact, it isnecessary to establish a geometric constraint,

where Rp is the radius of the parent nucleus.The third constraint is associated with the flux of

mass through the window connecting the two spheroids [seeFig. A]. During the evolution of the molecular phase of frag-ments, we are able to take a constant radius for the sphericalsegment corresponding to the nascent cluster (i.e., we havefixed R1 = R1) or a constant volume for both fragments asestablished by Eq. (2). We will return to this point later, whendiscussing the inertia associated with the degree of freedomof the relative motion subjected to the constrained relation-ships mentioned above.

The model considers explicitly the Coulomb and surfaceenergy contributions to the potential barrier. In our calculationwe have used Gaudin’s expression [61] for the electrostaticenergy of two overlapping spherical segments with a uniformcharge distribution,

Vc = 8

where ρc is the initial charge density, ε is a function of theangular variables x1 and x2, and a is the radius of the sharpneck. The variables x1 = π − θ1 and x2 = θ2 − π are definedin terms of the angles θ1and θ2, shown in Fig. A.

The expression for the ε factor in terms of the auxiliaryfunctions f , f ′, and g reads

where Zi e (i = p, 1, 2) are the nuclear charges, respectively,of the parent, emitted, and daughter nuclei. This definitionestablishes that the difference between the energies of theinitial and final configurations of the system reproduces theenergy released in the disintegration, the Q value, defined asQ = M − M1 − M2. The mass values in the Q-value expres-sion have been taken from the atomic mass evaluation by Audiet al. [57] when available, otherwise from the tables by Molleret al. [58]. Therefore, for the surface potential energy we have

Vs = σeff(S1 + S2), (9)

where the surface of each spherical segment is given by

Si = π Ri (Ri + δi ), (10)

3. GAMOW’S FACTOR AND DECAY HALF-LIFE

The quantum transition rate from the initial to the fi-nal state of the system has been determined by reducing theproblem to a one-dimensional motion like in Gamow’s alpha-decay theory. The penetrability factor is calculated under theassumption that the system tunnels a barrier of height V − Q.Shell effects, which appear in the Q value [already used inEq. (8)], act directly on the height and width of the effectivebarrier. The penetrability factor is calculated by

The limits of integration are the inner turning point

ζ0 = Rp − R1 (15)

and the outer one, which, for l = 0, is given by

ζc = Z1 Z2e2/Q. (16)

Finally, the half life is calculated as

τ = ln 2

λ(17)

with

λ = λ0P, (18)

where λ0 is a parameter of the model associated with the timescale of cluster preformation (in the case of cluster emission),or the surface oscillation characteristic time for the fissionprocess.

Rp = r0 A1/3p ,

where r0 is the most significant parameter used to adjust themodel to the set of experimental data. Values of r0 for differentapplications of the model together with the values of λ0 arepresented in Table A.

An additional constraint distinguishes two different de-scriptions for the mass transfer through the internal window.To characterize the varying mass asymmetry shape (VMAS)description, we regard the radius of the lighter fragment asconstant, i.e.,

R1 − R1 = 0, (20)

where R1 is the final radius of the light fragment. On the otherhand, in the constant mass asymmetry shape (CMAS) descrip-tion, the volume of each fragment radius is constant, and,in terms of the lighter fragment radius, volume conservationgives

1(ζ − ξ ) − (ζ − ξ )3 − 4R31 = 0. (21)

To determine Gamow’s penetrability factor we need toknow the inertia coefficient, µ, in Eq. (14). Werner-Wheeler’sapproximation [60] for the velocity field of the nuclear flowhas been mainly used in the literature [13, 62] to define the in-ertia tensor coefficient. In this approach, the velocity field hasbeen obtained from the solution of the continuity equation by

using the incompressibility and irrotationality of the nuclearflow. After reduction to the one-dimensional relative motionof the separating parts, only one component of the tensor be-comes relevant. The expression for Werner-Wheeler’s inertiacoefficient is given by

where ρ is the mass density for the system, and ζ is therelative velocity of the geometric center of the fragments.We can determine Werner-Wheeler’s inertia coefficient fortwo parametrizations, namely, µVMAS

WW and µCMASWW [13, 62].

An alternative proposal for calculating the inertia co-efficient has been recently applied in one-dimensional pen-etrability calculations [26]. By means of a straightforwardcalculation incorporating the constraints mentioned above[Eqs. (1), (2), (20), and (21)], the expression for the effectiveinertia coefficient reads

µeff = µα2, (23)

where µ = m1 × m2/(m1 + m2) is the reduced mass of thenascent fragments, and α is a configuration-dependent vari-able which characterizes the evolution of the system in themolecular phase. For the VMAS description one has

5. COMPARISON WITH EXPERIMENT

By using the VMAS and CMAS mass-transfer descriptionsand Werner-Wheeler’s and effective inertia coefficients wewere able to calculate the half-life values, τc, for the diffe-rent decay cases. All possible cases of spontaneous nuclearbreakup such that −7.30 � log10τc [s] � 27.50, and, at thesame time, log10 (τ/τc) > −17.0 (τ is the total half-life of theparent nucleus) have been considered. Calculations have beenperformed for all parent nuclei whose experimental mass val-ues are available in the atomic mass table evaluation by Audiet al. [57]. Whenever a daughter nucleus does not have itsmass value listed in Ref. [57], we have used the most re-cent mass prediction table by Moller et al. [58] as input data.The choice of the well-controlled parameters λ0 and r0 ofthe ELDM for each decay mode (proton, alpha, cluster emis-sions, and cold fission) has been made so that the quantity

σ =

is a minimum. Here, τexp represents the experimental half-life value, and N is the number of experimental data for thedecay mode under analysis. Thus, as discussed in Ref. [22],the values for both parameters λ0 and r0 have been determinedin order to obtain the best agreement with the experimentalhalf-life data (Table A).

Concerning the cases of proton emission from nuclei,Fig. B shows the half-life values for the most recent casesobserved in proton-rich emitters. Table B reports such dataas well as the calculated half lives in the framework of the cur-rent ELDM descriptions. In most cases a nonzero � value hasbeen chosen to give the best agreement between calculatedand measured half-life values (see Table B).

In Fig. C we show the variation of the half life ofproton emission for 156Ta, 161Re, and 171Au proton emittersas a function of the angular momentum. An increase of about10 orders of magnitude in the half-life values results when theorbital angular momentum varies from 0 to 10 -h.

out that the model combination VMAS/WW with r0 = 1.39 fmand λ0 = 1.5 × 1021 s−1 is the best choice to reproduce themeasured half-lives (filled circles in Fig. B). In this way, thedifferences between calculated and experimental values arenot greater than one order of magnitude.

For the sake of comparison with the most recent exper-imental half-life values of alpha decay, we have plotted theτc/τexp ratios in Fig. D. In spite of using only two parame-ters in the model, our theoretical results are comparable tothose obtained from other available models [71] in whichfour adjustable parameters are often used. Also, both modelparameterizations, VMAS/WW and VMAS/EFF, are able in re-producing quite well (σ = 0.38) the measured half lives forthe alpha-decay cases. The effect of the centrifugal barrieron the half life is smaller in the case of alpha decay thanin the case of proton emission, and this effect is smaller stillin the cases of heavier cluster emission. In Fig. E we displaythe variation of the half life of alpha decay (part a) and ofcluster emission (part b) for some experimentally observeddecay cases when � takes the values 0 -h and 6 -h.

The current ELDM has been used in cluster radioactiveprocesses for all cases of cluster emission from carbon tosilicon. The calculated half lives have been compared withthe experimental data (Fig. F). Equally good agreement withthe data is observed for the model combinations VMAS/WWand VMAS/EFF. The agreement becomes less satisfactory withthe CMAS parametrization, especially in the cases of emissionof clusters heavier than 20O. Previous systematic studies ofthe most probable nuclear decays by Poenaru et al. [14, 15]have considered only the cases for cluster emission modes.An intercomparison between the current and previous [14, 15]calculated half-life values is shown in Table C. The current

242

ELDM predictions are seen to be comparable (within 1–2orders of magnitude) to those calculated using the ASAFMroutine.

Although many theoretical and experimental studies oncold fission processes [74–76] have been carried out in thelast decade, there is not yet a systematic work that gives thepredicted half lives for the possible cases of these processesfor heavy parent nuclei.

In a previous work [23], a quite reasonable performanceof the ELDM has been achieved in some cases of cold fis-sion process, even when the values of model parameters λ0

and r0 were considered to be the same as those that wereadopted for cluster emission processes. In this work, the val-ues of model parameters for the cold fission process havebeen redefined in order to better reproduce the most recenthalf-life experimental results. The parent nuclei consideredfor this evaluation were 238,240,242Pu, 248Cm, and 252Cf; nu-clei for which the fragment total kinetic energy released andthe half life have been simultaneously determined (experi-mental results are given in Refs. [77, 78]). Because a hightotal kinetic energy of fragments have been observed in these

Experimental data are thosequoted in Ref. [22] for alpha decay and from Table C for cluster emission.

fission processes, they should be closely related to the coldnuclear fission process which can be described by the currentELDM.

By defining the mass asymmetry as

η = A2 − A1

A2 + A1, (33)

a cold fission process is, for the purpose of this work, thenuclear breakup into two fragments of mass numbers A1 andA2 (A2 > A1) such that η < 0.25. In Fig. G we representthe predicted total half-life values of cold nuclear fission fol-lowing the model parameterization VMAS/WW for all parentnuclei with available mass values in the 1997 mass table byAudi et al. [57] (as before, for daughter nuclei which do nothave the mass-value in the referred mass table we have usedthe most recent mass predictions by Moller et al. [58] as inputdata).

To obtain a better feeling concerning how the ELDMworks in the cases of fission processes, we focused attentionon the mass region near spherical fragments. There existsan experimentally explored fission process of some trans-Bk isotopes, for which cases the mass region of the fissionfragments is located nearby the doubly magic 132Sn isotope.In this process, the fragments possess a high kinetic energycompared to the systematic increase observed in ordinaryfission processes [77, 79]—the bimodal fission process [77].In some cases, the fragment mass distributions have been ex-perimentally determined. In Fig. H we compare the measured

mass distributions with the predictions from our ELDM. Inspite of the fact that the current model takes into account onlythe gross characteristics of cold fission, the locations of theexperimental maxima are well reproduced for nuclei that ex-hibit the bimodal fission process. Our results are extremelypeaked in the product mass region in the vicinity of 132Snbecause we are dealing strictly with cold fission processes,while the experimental distributions are inclusive ones in thefragment kinetic energy. This fact may be the reason for theside spreading of the experimental distributions as comparedwith our theoretical results. The most appropriate experimen-tal distribution to be compared with our result should be ex-clusive in the kinetic energy of fragments, i.e., distributionsof fragments with energies very near the Q value.

Finally, we present in a table the calculated half-liferesults of the four nuclear decay modes discussed above inthe framework of the ELDM for the model combination ofinertia coefficient and mass transfer description µVMAS

WW , andunder the assumption of zero angular momentum (the fewexceptions are for some cases of proton emission as explainedin Table B).

EXPLANATION OF TABLE

TABLE I. Calculated Q Values and Half Lives for the Most Probable Ground-State to Ground-State HadronicDecays of Nuclei throughout the Periodic Table

The table lists the calculated Q values and half lives for the most probable hadronic decays (ground-stateto ground-state transitions) of nuclei throughout the Periodic Table. The parent nuclei included in this tableare those with mass values available in the atomic mass evaluations by Audi et al. [57]. Calculations havebeen performed according to the shape parameterization VMAS and Werner-Wheeler’s inertia coefficient,and under the assumption of zero angular momentum (� = 0). In some cases of proton decay, however, anonzero � value has been chosen to give best agreement between calculated and measured half-life values.These � values are indicated near the calculated results by a superscript following the usual spectroscopicnotation, namely p ( � = 1), d (� = 2), f (� = 3), g (� = 4), and h (� = 5). Otherwise, � = 0 is implicit.Decay cases have been selected for calculated half life, τc (in seconds), such that −7.30 � log10τc � 27.50and log10( τ

τc) > −17.0, where τ is the total half life of the parent nucleus. Finally, for the cold fission cases,

printed here are only the fission modes of mass asymmetry η ≤ 0.04 (see Eq. (33)). The complete table isavailable as supplementary material in the journal website www.academicpress.com/adndt.

Z , Z1 Atomic numbers of the parent nucleus and emitted fragment (proton, alpha particle, heavy cluster,and/or cold fission fragment), respectively

A, A1 Mass numbers of the parent nucleus and emitted fragment, respectivelylog τ Decimal logarithm of the total half life, in seconds (half-life values are taken from the Lund/LBNL

Nuclear Data Search (Version 2.0, Feb. 1999), Department of Physics of the Lund University,and LBNL (Berkeley))

Q value Total energy available (in MeV) for the decay mode, as calculated from the Atomic Mass Evaluationby Audi et al. [57]; when the mass value of a daughter nucleus is not listed in Ref. [57] ithas been taken from the mass table by Moller et al. [58]

log τexp Decimal logarithm of the experimental half life (in seconds) of the indicated decay mode; thepartial, experimental half-life data are those quoted in Table B (proton emission), inRefs. [80–86] (alpha decay), and in Table C (cluster radioactivity)

log τc Decimal logarithm of the calculated half life (in seconds) for the decay mode according to theVMAS parametrization and Werner-Wheeler’s inertia coefficient of the current ELDM
