ResumoDifferential cross sections were measured at 8, 10, 12 and 14 MeV for elastic scattering of neutrons from enriched samples of 54Fe, 56Fe, 63Cu and 65Cu. Inelastic scattering to the first excited state in 54, 56Fe was also observed. For the 63, 65Cu isotopes, the inelastic cross sections for scattering to the combined group of the three (five) states were determined at 8 and 10 MeV (12 and 14 MeV). The elastic scattering data are compared to predictions of earlier global optical models. New spherical optical model representations were obtained. These data were combined with data for nickel, tin and lead to generate a new global parametrization. Comparisons of derived volume integrals for the potentials, total cross sections and potential radii are made to available information.
