Evaluation of iridium (n,xn) reactions

Abstract

Abstract. Recent experimental data, including detailed studies of the 191 Ir and 193 Ir metastable states have significantly improved our understanding of the nuclear structure for many iridium isotopes. Combining experimental γ production cross sections with the results of the reaction theory code GNASH, improved evaluations of neutron induced cross sections on several iridium isotopes have been completed. With a focus on improved descriptions of nuclear structure and pre-equilibrium modeling, 191 Ir(n, xn) cross sections are presented.
