The cross section of the reaction Sn112(α,γ)Te116 has been measured in the energy range of astrophysical interest for the p-process. Highly enriched self-supporting Sn112 foils were bombarded with α beams in the effective center of mass energy range from 7.59 to 11.42 MeV at the Notre Dame FN Tandem Van de Graaff accelerator. The characteristic activity of Te116 was counted with a pair of large volume Ge clover detectors in close geometry to maximize the detection efficiency. The cross section of the concurrent (α,p) reaction has also been measured. The results are compared with statistical model predictions for different global α-nucleus potentials.
