Total cross section measurements for the Pd-102(p, gamma)Ag-103 and Sn-116(p, gamma)Sb-117 reactions have been performed in the proton energy range 2.6 to 4.25 MeV, and for the Sn-112(alpha,gamma)T-116, reaction over the alpha beam energy range 7.0 to 10.5 MeV. An activation technique was used in which gamma rays from decays of the reaction products were detected off-line by two hyper-pure germanium detectors in a low background environment. Where possible, reaction rates are derived and the results compared to those of calculations generated by the NON-SMOKER and the MOST statistical model codes so as to judge their applicability for describing the cross sections needed for network calculations of nucleosynthesis in explosive astrophysical environments via the gamma- and rp-processes.
