Spin effects in the scattering of 1-GeV protons by nuclei

The elastic scattering of 1-GeV protons by ${}_{}{}^{58}{}_{}{}^{}\mathrm{Ni}$ and ${}_{}{}^{208}{}_{}{}^{}\mathrm{Pb}$ is analyzed using the first-order optical potential including the spin-orbit term. These potentials are generated using realistic nucleon-nucleon scattering amplitudes and nuclear densities with full isospin dependence maintained. The sensitivity of the differential cross sections and polarizations to the spin-orbit potentials and nuclear densities is investigated.
