Effects of cluster polarizations on the radiative capture reactions 3He(α,γ)7Be, 3He(α,γ)7Li, 6Li ( p,γ)7Be and 6Li (n,γ)7Li

Abstract

The microscopic three-cluster model, developed by the authors, was applied to study effects of cluster polarization on the capture reactions 3He(α ,γ )7Be, 3H(α ,γ )7 Li , 6 Li(p,γ )7Be and 6 Li(n,γ )7Li . These reactions are of great importance for the astrophysical applications. Thus main attention is devoted to the cross section (or astrophysical S factor) of the reactions at the low-energy range. We also study in detail correlations between astrophysical S factor of the reactions at zero energy and different quantities associated with the ground state of compound nucleus.
