Cross section measurements of α-induced reactions on Mo92,94 and Sn112 for p-process studies
Abstract
The Mo92(α,n)Ru95, Mo94(α,n)Ru97, and Sn112(α,γ)Te116 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 Sn112(α,γ)Te116 cross section agrees well with a recently measured thick-target cross section in the same energy range. For the Mo92,94(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.
