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

Angular distribution of the 6He(d,n)7Li reaction at Ec.m.=9.1 MeV is measured in inverse kinematics for the first time. The proton spectroscopic factors for the ground and first excited states of 7Li are derived by using the distorted wave Born approximation analysis. The astrophysical rates of 6He(p, γ)7Li reaction are then deduced and fitted with an expression of REACLIB.
