Abstract

Cross sections, analyzing powers and spin rotation parameters of proton elastic scattering from ^<58>Ni and ^<120>Sn have been measured at intermediate energies. In order to explain the ^<58>Ni data, it was necessary to use experimental density distributions deduced from charge distributions and to modify coupling constants and masses of σ and ω mesons. Assuming the same modification was also valid for ^<120>Sn and using proton densities deduced from charge densities, neutron density distribution was searched so as to reproduce ^<120>Sn data.
