【 摘 要 】

A unified microscopic approach based on the algebraic version of the resonating group model has been realized for description of the radiative capture reactions3H(α, γ)7Li and3He(α, γ)7Be, which play an important role for modern nuclear astrophysics. The astrophysical S-factors of the reactions and branching ratios between capture to the ground and first excited states of the7Li and7Be nuclei have been calculated. The comparison with the most recent experimental data demonstrates a good agreement.
