Systematic cross section measurements of alpha‐capture reactions at sub‐Coulomb energies relevant to the p process were performed in the Ge‐Sn region. At the same time a recent global α‐nucleus optical model potential (OMP) based on the double‐folding method was updated using all existing data on alpha elastic scattering and alpha‐induced reactions. In this paper, we report on our recent measurements of alpha‐capture reactions and present calculations using the improved alpha‐nucleus OMP.
