Abstract

The α--α differential cross sections are analyzed in the optical model using a double--folded potential. With the knowledge of this potential bound and resonance--state properties of α--cluster states in ⁸Be and ¹²C as well as astrophysical S--factors of ⁴He(α,γ)⁸Be and ⁸Be(α,γ)¹²C are calculated. Γ_γ--widths and B(E2)--values are deduced.
