Neutron total cross sections of elemental nickel were measured from 1.3 to 4.5 MeV, at intervals of ∼50 keV, with resolutions of 30 to 50 keV and to accuracies of 1 to 2.5%. Neutron differential-elasticscattering cross sections were measured from 1.45 to 3.8 MeV, at intervals and with resolutions comparable to those of the total cross sections, and to accuracies of 3 to 5%. The nonelastic-scattering cross section is derived from the measured values to accuracies of ≳6%. The measured results are shown to be in good agreement with the predictions of a model previously reported by the authors. The experimental results are compared with previously reported values, as represented by the Evaluated Nuclear Data File-B, Version-V, and areas of consistency and discrepancy noted.
