摘要：

The angular distribution of the C-12(Li-7,He-6)N-13 reaction at E(Li-7) = 44.0 MeV was measured at the HI-13 tandem accelerator of Beijing, China. The asymptotic normalization coefficient (ANC) of N-13 -> C-12 + p was derived to be (1.64 +/- 0.11) fm(-1/2) through the distorted wave Born approximation (DWBA) analysis. The ANC was then used to deduce the astrophysical S(E) factors and reaction rates for the C-12(p, gamma)N-13 direct capture reaction at energies of astrophysical relevance.
