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

Non-local optical potentials for the scattering of 200 MeV protons from 22 nuclei, ranging in mass from ⁶Li to ²⁰⁸Pb, have been defined 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 wavefunctions that specify the nuclear density matrices are Woods-Saxon functions for A ≤ 12 and harmonic oscillator functions thereafter. The resulting differential cross sections, analysing powers and spin rotations all compare well with the known data.
