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. Γγ--widths and B(E2)--values are deduced.
