Radiative р14N Capture to the Second and Fifth Excited States of 15O

Abstract

Within the framework of the modified potential cluster model, we have obtained a description of the available experimental data on the astrophysical S-factor of the p¹⁴N capture reaction to the second and fifth excited states of the ¹⁵O nucleus at 5.24 MeV and 6.86 MeV with J = 5/2⁺ for proton energies up to 1 MeV. Under the assumption that these excited states are D_5/2 levels and that the two resonances at 260 and 987 keV are D scattering waves, we have successfully reproduced the experimental data for the astrophysical S-factor. The calculations were performed in the energy range from 30 keV up to several MeV.
