Ab Initio Description of the Exotic Unbound 7He Nucleus

Simone Baroni,1,2,* Petr Navratil,2,3,† and Sofia Quaglioni3,‡

3Lawrence Livermore National Laboratory, P. O. Box 808, L-414, Livermore, California 94551, USA(Received 8 October 2012; revised manuscript received 19 November 2012; published 11 January 2013)

The neutron-rich unbound 7He nucleus has been the subject of many experimental investigations. While

the ground-state 3=2! resonance is well established, there is a controversy concerning the excited 1=2!

resonance reported in some experiments as low lying and narrow (ER " 1 MeV, ! # 1 MeV) while in

others as very broad and located at a higher energy. This issue cannot be addressed by ab initio theoretical

calculations based on traditional bound-state methods. We introduce a new unified approach to nuclear

bound and continuum states based on the coupling of the no-core shell model, a bound-state technique,

with the no-core shell model combined with the resonating-group method, a nuclear scattering technique.

Our calculations describe the ground-state resonance in agreement with experiment and, at the same time,

predict a broad 1=2! resonance above 2 MeV.

DOI: 10.1103/PhysRevLett.110.022505 PACS numbers: 21.60.De, 24.10.Cn, 25.10.+s, 27.20.+n

Exotic nuclei are the gateway to new manifestations ofnuclear matter at the boundaries of stability, where theneutron-to-proton ratios are larger or smaller than thosenaturally occurring on Earth. In these remote regions of thenuclear landscape, our ability to understand nuclear prop-erties in terms of the underlying forces is put to the test.Particularly interesting in this respect are systems acces-sible to many-body ab initio calculations, such as theneutron-rich isotopes of helium and, among them, 7He.Its ground state (g.s.), characterized by spin, parity andisospin J!T $ 3=2!3=2, lies at 0.430(3) MeV [1,2] abovethe threshold of a neutron (n) plus the 6He Borromean halo,a loosely-bound state of two neutrons and an " (4He)particle. Experimentally, excited states of 7He are popu-lated by means of transfer reactions that usually lead to acontinuous three-body background of 6He plus n (comingfrom the 7He decay) plus a third outgoing particle. Thepresence of such a background is a major stumbling blockand has left open questions about the low-lying spectrumof this nucleus. While there is a general consensus on theexistence of a 5=2! resonance centered at 3.35 MeV, whichmainly decays to "% 3n [3], the existence and position ofa low-lying 1=2! state are still under discussion. In par-ticular, many experiments [4–8] (most of which are basedon one-neutron knockout reactions of a 8He beam on acarbon target) advocate the presence of a narrow (! #1 MeV) 1=2! state at about 1 MeV while several others[9–14] do not confirm it. The occurrence of a low-lying1=2! state has also been excluded by a study on theisobaric analog states of 7He in 7Li [15]. According tothis work, a broad 1=2! resonance at "3:5 MeV with awidth of !" 10 MeV fits data the best. Neutron-pickupand proton-removal reactions [11,12] suggest instead a1=2! resonance at about 3 MeV with a width of! & 2 MeV.

From a theoretical standpoint, addressing the contro-versy surrounding the 1=2! resonance of 7He requires aunified description of structural and reaction properties thatcannot be realized within traditional ab initio bound-stateapproaches such as the Green’s function Monte Carlo(GFMC) method [16], the no-core shell model (NCSM)[17], or the coupled cluster method [18–20]. The complexcoupled cluster method was recently applied to He iso-topes, but only the g.s. of 7He was investigated [21]. In thisLetter, we address the low-lying resonances of 7He withinthe no-core shell model with continuum (NCSMC), a newunified approach to nuclear bound and continuum statesbased on the coupling of the NCSM [17] with the no-coreshell model combined with the resonating-group method(NCSM/RGM) [22–27]. The NCSM is a bound-state tech-nique, where one performs large-scale expansions of theA-body Schrodinger wave function in terms of a completeset of harmonic oscillator (HO) basis states. The A-bodysquare-integrable eigenstates jA#J!Ti are obtained bydiagonalizing the Hamiltonian matrix. The NCSM/RGMallows one to go beyond bound states and treat the con-tinuum of resonances, scattering states, and reactions byexpanding the A-body wave function over an (A! a, a)binary-cluster basis in the spirit of the RGM,

Scenario B – Status Quo, Increased Risk (Goals 1, 2, 3)

•  Subatomic physics program holds status quo but no investments into facility upgrades & international projects

•  Focus on rare isotope science, ATLAS, UCN - sacrifices elsewhere

•  Bare bones operations (cover fixed costs: detector lab, computing, seminars, visitors)

•  No matching of university investments into TRIUMF science (joint pos.)

•  No support of international endeavors or new science infrastructure

•  Budget impact on accelerator operations effects science

è reduced output resulting from lower availability

è less beam development, fewer new isotopes

Lost opportunities


Eroding leadership


Scenario C – reduced resources, restricted program (Goals 1,2,3) •  Laboratory concentrates research on particle and nuclear physics •  Reduce support for staff and operating activities with targeted, deep cuts •  Increased chances of major failure(s) leading to extended downtime

è  reduced science and HQP output, loss of users §  reduced RIB hours, unreliable operation ISAC users go elsewhere

è  loss of competitiveness, international leadership, and reputation; diminished relevance

§  ARIEL photo-fission beams substantially later than competition (GANIL, FRIB, FAIR) §  Fail to deliver on international commitment for UCN/nEDM §  Minimal contributions to international detector projects (ATLAS, T2K, …)

è Canada would lose capability to excel in Particle & Nuclear Physics, one of the drivers for its leading position in Physics and Astronomy

5-Year Plan 2015-2020 outlines the opportunities to build on demonstrated strength and invest into sustained excellence. Funding requested will enable TRIUMF to realize its vision:

•  Forefront rare isotope science program with ISAC and ARIEL (Goals 1,2 ✔)

•  Continued leading involvement in international particle physics projects and breakthrough discoveries (Goal 3 ✔)

•  Building the vision of the Electric Dipole Moment Lab (Goals1, 2, 3 ✔)

•  Help universities to strengthen Canadian community via joint positions

Sustained Excellence for Canada


è 5-Year Plan 2015-2020 further elevates Canada’s reputation and reinforces its leadership in Nuclear & Particle Physics

•  High impact science for Canada from 2008-2013 •  TRIUMF has made leading scientific contributions in subatomic physics •  TRIUMF has strengthened Canada’s reputation in the world through

•  exploitation of leading-edge infrastructures at TRIUMF •  leading scientific and technical contributions in international endeavors •  creating future leaders in Canada as well as internationally

•  Opportunities for Canada in 2015-2020 and beyond •  With strategic investments into world class research infrastructures and

highly skilled people •  TRIUMF will become the premiere ISOL facility for RIB science in the world •  Canadian scientists will make leading contributions to nuclear & particle

physics breakthroughs of the next 5-10 years

•  Securing long term Canadian leadership in nuclear & particle physics

Investing in sustained excellence and success for Canada
