Comparisons are made among results of calculations for intermediate-energy nucleon-nucleus scattering for {sup 12}C, {sup 16}O, {sup 40}Ca, {sup 90}Zr, and {sup 208}Pb, by use of optical potentials obtained from global Dirac phenomenology and from a microscopic Schroedinger model. Differential cross sections and spin observables for scattering from the set of five nuclei at 65 and 200 MeV have been studied to assess the relative merits of each approach. Total reaction cross sections from proton-nucleus and total cross sections from neutron-nucleus scattering have been evaluated and compared with data for those five targets in the energy range 20-800 MeV. The methods of analyses give results that compare well with experimental data in those energy regimes for which the procedures are suited.
