Abstract

Studies of the bremsstrahlung spectrum-weighted average yields of \({}^{187}\) Os( \(\gamma,p\) ) \({}^{186}\) Re, \({}^{189}\) Os( \(\gamma,p\) ) \({}^{188}\) Re, and \({}^{190}\) Os( \(\gamma,p\) ) \({}^{189}\) Re were conducted, and experimental values of these yields were obtained for a bremsstrahlung cutoff energy of 23 MeV. The results of simulation within the statistical nuclear model using the TALYS1.96 software code indicate a predominant contribution of nonstatistical mechanisms to the reactions under study. Calculations of the yields of the reactions, semidirect processes taken into account, describe the experimental data satisfactorily.
