Reaction rate of p14N → 15Oγ capture to all bound states in potential cluster model

Review of calculation results for astrophysical S-factor of the N-14(p,gamma)O-15 capture reaction in the p(14)N channel of O-15 was presented. It was carried out in the frame of the modified potential cluster model (MPCM) taking into account resonances in the O-15 spectrum up to 3.2MeV at energy of incident protons varying of 30 keV to 5MeV. It is possible to describe experimental data for the astrophysical S-factors of the radiative proton capture on N-14 to five excited states of O-15 at excitation energies of 5.18MeV to 6.86MeV, only under assumption, that all five resonances are D scattering waves. Quality new physical interpretation of the capture mechanism is discussed in this channel to the ground state of O-15. We assumed that the ground state of O-15 is determined by the p(14)N* channel with excited N-14* cluster, which immediately allowed us to correctly describe order of values of the experimental S-factor for capture to this state. Taking into account these results, the total S-factor of the proton capture on N-14 and the reaction rates to the ground and five excited states of O-15 were determined at temperatures of 0.01 T-9 to 10 T-9. The parametrization of the total reaction rate with a simple form is performed, which allows as to obtain chi(2) equal to 0.06 with 5% errors of the calculated rate.
