Radiative capture reactions description using the algebraic versions of the resonating group model and the orthogonality conditions model

Abstract

Abstracts-An approximate approach that combines the algebraic versions of the resonating group model and the orthogonality conditions model is developed for description of radiative capture reactions. The approach is applied to the mirror 3 H(α, γ) 7 Li and 3 He(α, γ) 7 Be reactions. Astrophysical S factors and branching ratios are calculated for these reactions. The nuclear interaction of the nucleons is described, using the modified Hasegawa-Nagata potential. The obtained results agree well with the experimental data, prov ing the applicability of the proposed approach to the describing radiative capture reactions and offering pros pects for its further application.
