Scientific paper

The radiative capture cross sections for 3He(α, γ)7Be and 3He(α, γ)7Li at astrophysical energies have been studied microscopically in terms of the resonating group method. It was found that the astrophysical S-factors correlate strongly to the nuclear size and deformation of 7Be and 7Li. With the help of measured nuclear properties of these nuclei, a safety range of the absolute values of the S-factor was determined; the most recommended S(0)-values are 0.50 +/- 0.03 keV . b for the 3He(α, γ)7Be reaction and 0.098 +/- 0.006 keV . b for the 3H(α, γ)7Li reaction.
