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 E _c.m.=6.7 MeV. This value is then used to compute the direct component of the astrophysical ⁶Li(p, γ) ⁷Be _g.s. S( E) factors and determine the resonance parameters from the total S( E) factors.
- big bang nucleosynthesis,
- spectroscopic factor,
- proton radioactive capture reaction
