Astrophysical S-factor for alpha-Capture of (113)In in the p-Process Energy Range

Abstract

The cross sections of (113)In(alpha, gamma)(117)Sb and (113)In(alpha,n)(116)Sb reactions have been measured using the activation method. The experiments were carried out at the ATOMKI cyclotron accelerator in the center of mass energy range from 8.7 to 13.7 MeV. Astrophysical S-factors have been calculated, and preliminary results are compared With statistical model predictions.
