Abstract

The production cross-sections of Sn-117m,Sn-113 radioisotopes for proton-induced reactions on natural tin were measured up to 40 MeV by using a stacked-foil activation technique at the MC50 cyclotron of the Korea Institute of Radiological and Medical Sciences. The thick target integral yields were also deduced for each radionuclide by using the measured cross-sections from the respective threshold up to 40 MeV. The present results are in generally good agreement with the earlier reported data and with the theoretical data calculated by using the computer codes TALYS and ALICE-IPPE. The production yield of Sn-117m from a natural tin target at a 39 MeV proton energy was 3.15 MBq/mu A-h (85.14 mu Ci/mu A-h), but the impurity level due to the long-lived Sn-113 radionuclide was found to be similar to 4 %.
