Excitation functions of 186,187,188,189,190,192Ir formed in proton-induced reactions on highly enriched 192Os up to 66 MeV

Abstract

Cross sections of proton-induced nuclear reactions on highly enriched 192Os were measured up to 66 MeV by using the stacked-foil irradiation technique. Excitation functions are presented for the reactions 192Os(p,n) 192Ir, 192Os(p,3n) 190Ir, 192Os(p,4n) 189Ir, 192Os(p,5n) 188Ir, 192Os(p,6n) 187Ir and 192Os(p,7n) 186Ir. No earlier experimental cross-section data could be found in the literature except for the 192Os(p,n) 192Ir process. Our new experimental results are compared with theoretical predictions by means of the theoretical model code ALICE/ASH. Integral thick-target yield calculations were also performed for the 192Os(p,n) 192Ir and 192Os(p,3n) 190Ir reactions to evaluate the 190Ir contamination level, as a function of energy, in the case of 192Ir productions.
