Cross section measurements of {alpha}-induced reactions on {sup 92,94}Mo and {sup 112}Sn for p-process studies

The {sup 92}Mo({alpha},n){sup 95}Ru, {sup 94}Mo({alpha},n){sup 97}Ru, and {sup 112}Sn({alpha},{gamma}){sup 116}Te cross sections were measured at the upper end of the p-process Gamow window between 8.2 and 11.1 MeV. Our results are slightly lower than global Hauser-Feshbach calculations from the code NON-SMOKER, but still within the uncertainty of the prediction. The {sup 112}Sn({alpha},{gamma}){sup 116}Te cross section agrees well with a recently measured thick-target cross section in the same energy range. For the {sup 92,94}Mo({alpha},n) reactions the present data close to the reaction thresholds could eliminate previous uncertainties within a factor of 20, and we can present now useful comparisons to statistical model calculations with different optical potentials.
