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

摘要

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 3H(α, γ)7Li and 3He(α, γ)7Be 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, proving the applicability of the proposed approach to the describing radiative capture reactions and offering prospects for its further application.
