  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 114Sn(p,{\alpha})111In, {^{120}}Sn(p,{\alpha})117gIn,
and 114Sn(p,x)113Sn 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 120Sn(p,{\alpha})117m,gIn reactions where the
numerical calculations are shifted to higher energies. We also measure isomeric
cross section ratios for 117m,gIn and 120m,gSb pairs as functions of the
incident proton energy.
