Amplitude of Scattering of Protons on the Bounded Nuclear Nucleons from Analysis of the Proton-Nucleus Scattering

The results of calculations and their comparison with experimental data of proton scattering on 12 C, 40 Ca, 58 Ni and 208 Pb nuclei at energies from 200 to 1000 MeV are investigated based on the optical potential model in which the amplitude of scattering of an incident proton on a bound nuclear nucleon is explicitly revealed. This amplitude depends on three parameters, namely, the total nucleon-nucleon scattering cross section, the ration of real to imaginary parts of scattering amplitude at forward angles, and on the slope parameter. This analysis of proton-nucleus scattering data allows one to establish these parameters and compare them with those from the analysis of proton scattering on a free unbounded nucleon.
