摘要
Angular distributions of H-2(He-6,Li-7)n and C-12(Li-7,He-6)N-13 reactions were measured at the HI-13 tandem accelerator, Beijing. Asymptotic normalization coefficient (ANC) of N-13 -> C-12 + p was derived to be 1.64 +/- 0.11 fm(-1/2) through distorted wave Born approximation (DWBA) analysis, which was then used to deduce the astrophysical S(E) factors for direct capture in C-12(p,gamma)N-13 at energies of astrophysical relevance.
