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)⁷Li, ⁶Li(p, γ)⁷Be and ⁶Li(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.

Keywords: three-cluster model, cluster polarization, capture reaction, astrophysical S factor.
