Study of Activation of $${}^{{186,188,189}}$$Re in ($${\gamma},{p}$$) Reactions

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.
