Abstract

Abstract: We studied the excitation functions of residual radionuclides produced via proton and deuteron bombardment on natural iridium in the energy ranges of 30–15 MeV and 50–15 MeV, respectively. A conventional stacked-foil activation technique combined with HPGe γ-ray spectrometry was used to measure the excitation functions for 189, 191 Pt and 189, 190g, 192g, 194g Ir radionuclide production. Theoretical thick target yields were estimated to be 172 MBq/µA h and 192 MBq/µA h via the 193 Ir(p, 3n) 191 Pt reaction at 29.6–17.5 MeV and the 193 Ir(d, 4n) 191 Pt reaction at 40.3–23.8 MeV, respectively. The feasibility of 191 Pt production from an iridium target was discussed, and compared with previously reported methods for the production of 191 Pt. Highlights: Excitation functions for 189, 191 Pt and 189, 190g, 192g, 194g Ir radionuclide production were measured. Theoretical thick target yields were estimated to be 172 MBq/µA h and 192 MBq/µA h via the 193 Ir(p, 3n) 191 Pt reaction at 29.6–17.5 MeV and the 193 Ir(d, 4n) 191 Pt reaction at 40.3–23.8 MeV, respectively.
