Status and recent results with nucleon probes

Some recent results of Kerman, McManus, and Thaler optical potential analyses of 0.8 GeV polarized proton elastic scattering data on a wide range of target nuclei are presented. Second order corrections due to target nucleon correlations and electromagnetic effects are discussed and are included in the analysis presented. Neutron radii and density distributions deduced from the 0.8 GeV proton elastic data are compared with the results of analyses of 1.0 GeV proton scattering data and with Hartree-Fock predictions. Approximately model-independent forms for the neutron densities are obtained and are compared with theoretical calculations. Good agreement with Hartree-Fock predictions is attained in most cases. 49 references
