Neutron Cross-Section Evaluations for ~(70,72,73,74),76Ge

摘要

Entirely new evaluations have been performed for neutrons on all isotopes of Ge, from a thermal energy up to 20 MeV, with a focus on photon production. The resonance parameters were considerably improved compared to earlier evaluations. The fast-neutron region has been evaluated using the EMPIRE-2.19 code. The results were validated against photon data on Fe and Nb. Isotopic evaluations for Ge were summed up and compared with available measurements on natural Ge. Various quantities related to photon production, showing strong dependence on neutron incident energy, are discussed.
