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.
