Coulomb wave functions for all real η and ϱ

Abstract

The S-factor of radiative p12N capture at energies from 20 keV to 5 MeV was considered within the modified potential cluster model with forbidden states, considering the first resonance at Ex = 2.69(5) MeV. It was shown that one can obtain the astrophysical S-factor based on potentials consistent with the bound state energies and asymptotic constant values. According to the theoretical total cross sections, the calculation of the p12N capture reaction rate is made at temperatures from 0.001 to 10 T9. The calculated results for the reaction rate are approximated by analytical expression, which simplifies their use in applied research.
