Abstract
Angular distribution of the Li 8 ( d , p ) Li g.s. 9 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 , γ ) C 9 at energies of astrophysical relevance using the ANC for C 9 → B 8 + p extracted from the mirror system.
