FULLY MICROSCOPIC MODEL ANALYSES OF THE ELASTIC-SCATTERING OF 200 MEVPROTONS FROM TARGETS OF DIVERSE MASS

Non-local optical potentials for the scattering of 200 MeV protons fro m 22 nuclei, ranging in mass from Li-6 to Pb-208, have been defined by folding a complex, medium-dependent effective interaction with densit y matrix elements of each target. The effective interaction is based u pon solutions of the Lippmann-Schwinger and Brueckner-Bethe-Goldstone equations having the Paris potential as input. The bound-state single- particle wavefunctions that specify the nuclear density matrices are W oods-Saxon functions for A less than or equal to 12 and harmonic oscil lator functions thereafter. The resulting differential cross sections, analysing powers and spin rotations all compare well with the known d ata.
