Fully microscopic model analyses of the elastic scattering of 200 MeV protons from targets of diverse mass

Nonlocal optical potentials for the scattering of 200 MeV protons from 22 nuclei, ranging in mass from 6Li to 208Pb, have been identified by folding a complex, medium dependent effective interaction with density matrix elements of each target. The effective interaction is based upon solutions of the Lippmann-Schwinger and Brueckner-Bethe-Goldstone equations having the paris potential as input. The bound state single particle wave functions that specify the nuclear density matrices are Woods-Saxon functions for A≤12 but harmonic oscillator functions thereafter. The Wood-Saxon potential parameters and harmonic oscillator lengths were determined from fits made to the elastic electron scattering form factors for the low mass nuclei (A≤ 20) and by finding our best fits to the proton scattering data for the nuclei of heavier mass. The resulting differential cross sections, analyzing powers and spin rotations all compare well with the known data. 38 refs., 2 tabs., 12 figs
