Radiative capture in 4He12C channel of 16O nucleus in the potential cluster model

Abstract

Radiative capture processes in 4He12C channel of 16O nucleus are considered on the basis of potential two-cluster model with intercluster interactions which contain forbidden states and reproduce phase shifts of elastic scattering and some characteristics of bound states. Astrophysical S-factors are calculated at low energies. It was shown that the model used enables to describe the total cross-sections of the photoprocesses.
