Folding model approach to the elastic p+12,13C scattering at low energies and radiative capture 12,13C(p,γ) reactions.

The proton radiative capture 12,13C (p , γ) reactions at astrophysical energies, key processes in the CNO cycle, are revisited in the potential model with the proton-nucleus potential for both the scattering and bound states obtained in the folding model, using a realistic density dependent nucleon-nucleon interaction. For the consistency, this same folding model is also used to calculate the optical potential of the elastic p + 12 , 13 C scattering at energies around the Coulomb barrier. The folded p + 12 , 13 C optical potentials are shown to account well for both the elastic p + 12 , 13 C scattering and astrophysical S factors of the radiative capture 12,13C (p , γ) reactions.
