Cross sections for proton-induced reactions on Pd isotopes at energies relevant for the gamma process
Abstract
Proton-activation reactions on natural and enriched palladium samples were investigated via the activation technique in the energy range of Ep=2.75 MeV to 9 MeV, close to the upper end of the respective Gamow window of the gamma process. We have determined cross sections for 102Pd(p,gamma)103Ag, 104Pd(p,gamma)105Ag, and 105Pd(p,n)105Ag, as well as partial cross sections of 104Pd(p,n)104Agg, 105Pd(p,gamma)106Agm, 106Pd(p,n)106Agm, and 110Pd(p,n)110Agm with uncertainties between 3% and 15% for constraining theoretical Hauser-Feshbach rates and for direct use in gamma-process calculations.
