摘要：

Angular distribution of the Li-8(d, p)Li-9(g.s). reaction at E-cm = 7.8 MeV was measured in inverse kinematics. The square of asymptotic normalization coefficient (ANC) for the virtual decay Li-9 -> Li-8 + n was derived to be 1.33 +/- 0.33 fm(-1) through distorted wave Born approximation (DWBA) analysis, for the first time. According to charge symmetry, (ANC)(2) for C-9 -> B-8 + p was then extracted to be 1. 14 +/- 0.29 fm(-1). We have deduced the astrophysical S-factors and reaction rates for direct capture in B-8(p, y)C-9 at energies of astrophysical relevance using the ANC for C-9 -> B-8 + p extracted from the mirror system.
