Probing the production mechanism of the light p-process nuclei
Abstract
In an effort to investigate the production of 74Se in p-process nucleosynthesis, the 74Ge(p,γ)75As reaction cross section was measured in the relevant energy range of Ep=1.6-4.2 MeV. The measurements were carried out using the NSCL SuN detector at the University of Notre Dame. The results are in good agreement with previous work, extending the measurements to both lower and higher energies. The measurements are compared to theoretical predictions using the non-smoker and talys nuclear reaction codes. New and improved reaction rates are offered, and these reaction rates are used in a 25M⊙ Type II Supernova model to study their impact on the production of 74Se.
