Abstract

The simulation of p-process nucleosynthesis requires thousands of reaction rates. These rates are typically calculated with the statistical Hauser Feshbach Model (HF-Model) which depends critically on the reliability of the optical nucleus potential. In particular, the predicted (α,γ) cross sections at low energies (below 20 MeV) are sensitive to the choice of the alpha potential. Dscrepancies have been observed between the experimental cross sections and the theoretical values (NON-SMOKER). Currently, only a few α-induced reaction rates have been measured. To explore the trend 106Cd(α,γ)110Sn and 112Sn(α, γ)116Te cross sections were measured at the Notre Dame FN Tandem accelerator. First results are presented and discussed.
