“Plus” of the TH methods

1 ) Typical QF process cross sections (mbarn/sr) though measuring astrophysical ones

2) The TH cross sections is the purely NUCLEAR one: no Coulomb barrier effects

3) No electron screening effects: an INDEPENDENT piece of information can be obtained on the electron screening potential Ue by comparison to direct data

4) Can be extended to use QFR for studying NEUTRON induced reactions (VNM Virtual Neutron Method)

“Minus” of the TH methods

1 ) Competition between QF and other reaction mechanisms: identification of the convenient kinematical conditions may need more than one experiment run

2) Some dependence on theoretical models

3) Need of direct data at higher energies for normalization

S. Cherubini et al., ApJ 457 (1996) 855

Several tests performed: Starting from low mass nuclei… Break-up in the target or in the projectile

Use of different TH nuclei

Check of the hypothesis of the bare nuclear cross section

Resonances

… going to higher mass nuclei Study of reactions involving heavy nuclei

Study of neutron induced reactions

Study of radioactive nuclei induced reactions

TH results: pole-invariance effects

6Li Break-Up 3He Break-Up

TH results: Big Bang Nucleosynthesis (BBN)

Comprehensive fit of S(E) including direct (high-energy) and THM (low-energy) data;

Evaluation of the burning reaction rates; Time evolution of the abundances; Confirmation of the long-standing lithium-problem

in astronomy and cosmology.

TH results: 6Li in pre-Main Sequence Stars

- Variation of about 15% (blue line) at astrophysical temperatures relevant for Li-burning in stars;

- Astrophysical simulation for 6Li abundances (challenge for stellar observations)

TH results: 10B(p,a)7Be

The absolute value of the astrophysical factor has been determined, giving, for the first time, a measurement at the corresponding Gamow peak. The THM S(E) factor has been used to evaluate the electron screening potential value
