YIELD ANALYSIS OF RESIDUES FROM ¹²C+⁹³Nb REACTION: PRODUCTION OF MEDICALLY IMPORTANT ^101mRh VIA ¹⁰¹Pd

Production of Rh-101m radionuclide, which is a preferred candidate for diagnostic imaging and radiotherapy, has been reported from a heavy-ion reaction C-12+Nb-93. In addition to its formation as an evaporation residue of Ag-105(*) compound nucleus, it was formed significantly through electron capture decay of its precursor Pd-101 within the 39.5-75.9 MeV range. Followed by activation, ?-ray spectroscopy was employed to identify evaporation residues. A maximum yield of 793.4 and 89.4 MBq/C at 71.0 MeV was measured for Pd-101 and Rh-101m, respectively, along with other co-produced radionuclides. The conditions for optimizing the yield of Rh-101m to ensure its purity have been discussed. Subsequently, the thick target yield for Rh-101m is estimated using the model code EMPIRE-3.2.2.
