Evaluation of neutron nuclear data on hafnium isotopes for JENDL-4

Shibata, Keiichi

Neutron nuclear data on $^{174,176,177,178,179,180,181,182}Hf$ have been evaluated for the evaluated nuclear data library JENDL-4 in the energy region from $10^{-5}$ eV to 20 MeV. The resolved resonance parameters of the previous library were updated by considering recent measurements. The statistical model was applied to calculate the cross sections above the resolved resonance region. Neutron transmission coefficients were obtained by the coupled-channel method, together with the total cross sections, the shape elastic scattering cross sections and the direct-reaction components of inelastic scattering cross sections. Preequilibrium and direct-reaction processes were taken into account in addition to the compound process. The present evaluation is almost consistent with available experimental data, and it is compiled into JENDL-4.
