Abstract

The mirror seven-nucleon He4+H3 and He4+He3 systems are studied microscopically using the algebraic version of the resonating group model. Astrophysical S factors and branching ratios for the H3(α,γ)Li7 and He3(α,γ)Be7 radiative captures are calculated in a wide energy range from ultralow energies to intermediate ones covering the Li7 and Be7 lowest resonance states. All allowed E1, E2, and M1 captures from s, p, d, and f waves are taken into account in the calculations. Nuclear phase shifts for the H3(α,α)H3 and He3(α,α)He3 s-, p-, d-, and f-wave elastic scattering are computed. Properties of the bound and low-lying resonance states of the Li7 and Be7 nuclei are considered. The obtained results are compared with data from experiments.
