Abstract
Calculations were performed to support method development for simultaneous production of Ni and Ir isotopes. The work scope included development of the physical target, irradiation configuration, and post-irradiation radiochemical separations. The assumptions of predictive models previously developed were refined based upon the precise experimental configuration selected, including Os target material and a set of stacked targets for concurrent production of Ni and Ir isotopes. Model predictions of the reaction cross sections with EMPIRE 3.2 (Herman in Nuclear Data Sheets 108:2655–2715, 2007) and implied isotopic yields are compared with proton beam irradiation measurements to refine model parameters and guide future experiments.
