  • The ‘lithium problem’ in Big Bang nucleosynthesis (BBN) has recently focused on reactions involving 7Be. The 6Li(p, γ)7Be reaction can provide us not only with information about 6Li destruction but also with information about 7Be production. In the present work, the proton spectroscopic factor in 7Be is extracted to be 0.70±0.17 from the angular distribution of 7Be(d, 3He)6Li at Ec.m.=6.7 MeV. This value is then used to compute the direct component of the astrophysical 6Li(p, γ)7Beg.s. S(E) factors and determine the resonance parameters from the total S(E) factors.

Abstract: The ‘lithium problem’ in Big Bang nucleosynthesis (BBN) has recently focused on reactions involving 7Be. The 6Li(p, γ)7Be reaction can provide us not only with information about 6Li destruction but also with information about 7Be production. In the present work, the proton spectroscopic factor in 7Be is extracted to be 0.70±0.17 from the angular distribution of 7Be(d, 3He)6Li at Ec.m.=6.7 MeV. This value is then used to compute the direct component of the astrophysical 6Li(p, γ)7Beg.s. S(E) factors and determine the resonance parameters from the total S(E) factors.
