Neutron total cross sections are measured with broad resolutions (50 to 100 keV) from approx. = 1.0 to 4.5 MeV at intervals of less than or equal to 50 keV and to accuracies of approx. = 1%. Differential elastic scattering cross sections are measured at greater than or equal to 10 scattering angles distributed between 20 and 160/sup 0/ from approx. = 1.5 to 4.0 MeV at intervals of less than or equal to 50 keV. Angle-integrated elastic scattering cross sections are deduced from the measured values to accuracies of greater than or equal to 5%. Inelastically scattered neutrons are observed up to incident neutron energies of 4.0 MeV at scattering angles distributed between 20 and 160/sup 0/. Cross sections are determined corresponding to the excitation of observed states at: Chromium - 1433, 2377, 2665, 2778, and 2970 keV; Iron - 853, 1389, 2097, 2579, 2677, 2974, and 3152 keV; and /sup 60/Ni - 1342, 2168, 2304, 2509, 2636, and 3164 keV. The experimental results are discussed in terms of conventional optical-statistical models and in the context of direct-scattering processes. The experimental and calculational results are compared with the corresponding evaluated quantities given in the ENDF/B file. 21 references.
