New evaluation of neutron nuclear data for zinc isotopes

Iwamoto, Nobuyuki  

New evaluation of neutron-induced nuclear data for five stable isotopes of zinc (mass numbers A=64, 66, 67, 68, and 70) is consistently carried out in the incident neutron energy range from eV up to 20 MeV. In the low energy region up to about 100 keV resolved resonance parameters are evaluated by taking account of available measurements. In the fast energy region the comprehensive calculations with nuclear reaction models, in which compound, preequilibrium and direct processes are taken into account, are performed to estimate cross sections for various reactions and double differential cross sections of emitted neutrons and -rays. The comparisons of the evaluated cross sections with experimental data and existing evaluated nuclear data libraries are made and reveal a good reproducibility of measurements.
