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