Proton induced reactions on 114Sn and 120Sn targets at energies up to 18 MeV

We measure cross sections of proton-induced reactions on tin up to energies of 18 MeV using the stacked-foil activation technique, and report first experimental values for Sn-114(p,alpha)In-111, Sn-120(p,alpha)In-117g, and Sn-114(p,x)Sn-113 reactions. Measured cross sections have been compared to existing experimental values and numerical calculations based on Talys1.95. Our data are in good agreement with all previous experiments, and also with Talys1.95 results except for Sn-120(p,alpha)In-117m,In-g reactions where the numerical calculations are shifted to higher energies. We also measure isomeric cross section ratios for In-117m,In-g and Sb-120m,Sb-g pairs as functions of the incident proton energy.
