Abstract

Proton-activation reactions on natural and enriched palladium samples were investigated via the activation technique in the energy range of ${E}_{p}=2.75$--9 MeV, close to the upper end of the respective Gamow window of the $\ensuremath{\gamma}$ process. We have determined cross sections for ${}^{102}$Pd$(p,\phantom{\rule{-0.16em}{0ex}}\ensuremath{\gamma})$${}^{103}$Ag, ${}^{104}$Pd$(p,\phantom{\rule{-0.16em}{0ex}}\ensuremath{\gamma})$${}^{105}$Ag, and ${}^{105}$Pd$(p,\phantom{\rule{-0.16em}{0ex}}n)$${}^{105}$Ag, as well as partial cross sections of ${}^{104}$Pd$(p,\phantom{\rule{-0.16em}{0ex}}n)$${}^{104}$Ag${}^{g}$, ${}^{105}$Pd$(p,\phantom{\rule{-0.16em}{0ex}}\ensuremath{\gamma})$${}^{106}$Ag${}^{m}$, ${}^{106}$Pd$(p,\phantom{\rule{-0.16em}{0ex}}n)$${}^{106}$Ag${}^{m}$, and ${}^{110}$Pd$(p,\phantom{\rule{-0.16em}{0ex}}n)$${}^{110}$Ag${}^{m}$ with uncertainties between 3% and 15% for constraining theoretical Hauser-Feshbach rates and for direct use in $\ensuremath{\gamma}$-process calculations.
