Abstract: Sn-117m is one of the radioisotopes can be beneficially produced through alpha particle irradiation. The targets were prepared by deposition of Cd-116 metal onto high purity 12 mu m thick Cu backing. The average deposited thickness was 21.9 mu m. The beam energy was thoroughly measured by Time of Flight (TOF) methods and proved to be 51.2 MeV. For the experiment the well-established stacked foil technique was used. In addition to the Cd targets, Ti foils were also inserted into the stacks for energy and intensity monitoring. The Cu backings were also used for monitoring and as recoil catcher of the reaction products from the cadmium layer. The activities of the irradiated foils were measured with HPGe detector for gamma-ray spectrometry and cross section values were determined. As a result excitation functions for the formation of Sn-117m, In-117m,In-g, In-116m In-115m and Cd-115m,Cd-g from enriched Cd-116 were deduced and compared with the available literature data and with the results of the nuclear reaction model code calculations EMPIRE 3.2 and TALYS 1.8. Yield curves were also deduced for the measured nuclear reactions and compared with the literature.
