Astrophysical S factor C-13(p,gamma)N-14 and asymptotic normalization coefficients.

Original language description

We reanalyze the C-13(p,gamma)N-14 radiative capture reaction within the R-matrix approach. The low-energy astrophysical S factor has important contributions from both resonant and onresonant captures. The normalization of the nonresonant component of the transition to a particular N-14 bound state is expressed in terms of the asymptotic normalization coefficents (ANC). In the analysis we use the experimental ANC`s inferred from the C-13(N-14,C-13)N-14 and C-13(He-3,d)N-14 reactions. The fits of the calculated S factors to the experimantal data are sensitive to the ANC values and are used to test the extracted ANC`s. We find that for transitions to all the states in N-14, except the excited state, the ANC`s determined from the transfer reactions provide the best fit. The astrophysical factor we obtain, S(0)=7.7+/-1.1 keV b, is in excellent agreement with previous results.
