摘      要：In order to investigate the elastic scattering,we fit scattering observables of the weighted fits(WF16)with the relativistic Love-Franey(RLF)*** masses,cutoff parameters,and initial coupling strengths of RLF are assumed to be independent of *** the energy boundary between low energy and high energy is around 200 Me V,the masses,cutoff parameters,and initial coupling strengths of RLF are obtained by fitting scattering observables of WF16 at an incident energy of 200 *** the masses,cutoff parameters,and initial coupling strengths as the input,the energy-dependent RLF model is constructed over the laboratory energy range of 20 to 800MeV within a unified *** examine the validity of this fit,we investigate p+^(208)Pbelastic scattering for various *** the scattering observables of pp and pn of 200 MeV best fit the values of WF16,the RLF model of 200 MeV without the Pauli blocking(PB)corrections fails to describe the experimental differential cross sections,analyzing powers,and spinrotation *** the PB corrections are taken into account for various energies,the RLF model can well describe the experimental data of p+^(208)Pbelastic scattering.
