Measurements of the Differential Cross Sections for Elastic and Inelastic Scattering of 14-MeV Neutrons in Natural Chromium, Iron, Nickel, and Niobium

摘要

The Time-of-tlight techique was used with the "righ" scattering geometry in a laboratory with low neutorn-scattering backgorund to measure the angular distributions of the corss sections for elastic and inelastic scattering of 14-MeV neutrons in antural chromium, iron, nickel, and niobium. Specifically for inelastic scattering, the measurements included the 1.43- and 4.56-MeV levels of ~52Cr; the 0.85-, (2.94 to 3.12)-, and (4.46 to 4.51)-MeV levle groups of ~56fp.e; the 1.33-MeV level of ~60Ni combined with the 1.45-MeV levle of ~58Ni; and the 4.48-MeV level of ~58Ni.
