Determination of the 12C(p, γ)13N reaction rates from the 12C(7Li,6He)13N reaction

The angular distribution of the 12C(7Li,6He)13N reaction at E(7Li) = 44.0 MeV was measured at the HI-13 tandem accelerator of Beijing, China. The asymptotic normalization coefficient (ANC) of 13N → 12C + 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 12C(p, γ)13N direct capture reaction at energies of astrophysical relevance.
