The (92)Mo(alpha, n)(95)Ru, (94)Mo(alpha, n)(97)Ru, and (112)Sn(alpha, gamma)(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 (112)Sn(alpha, gamma)(116)T, cross section agrees well with a recently measured thick-target cross section in the same energy range. For the (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.
