The ³ H(α, γ)⁷ Li and ³He(α, γ)⁷ Be Radiative Capture Reactions in a Wide Energy Range

Abstract

The mirror 3 H(α, γ)7 Li and 3 He(α, γ)7 Be reactions are considered from the microscopic viewpoint within a developed approach based on the multiscale algebraic version of the resonating group model. The total astrophysical S factors and the branching ratios for these reactions are calculated at low and intermediate energies covering the lowest resonances of the final fused nuclei. The results from the calculations are in an agreement with data from experiments.
