Elastic scattering of polarized protons from 58Ni at Ep=192, 295, and 400 MeV
Abstract
Elastic scattering of polarized protons from 58Ni has been measured at incident proton energies of 192, 295, and 400 MeV. Optical model calculations employing relativistic impulse approximations and a microscopic folding model using a nonrelativistic G matrix are compared with the experimental results. In order to explain the experiment further, it is necessary to use a density distribution deduced from the charge distribution measured by electron scattering and to modify the nucleon-nucleon interaction in the nuclear medium by altering coupling constants between nucleons and mesons and also adjusting the masses of exchanged mesons.
