Abstract：
This paper is based on a suggestion by Franco and Yin that the phase of the ucleon-nucleon scattering amplitude should vary with momentum transfer .The intermediate energy proton elastic scattering on 4He is studied applying the KMT multiple scattering theory with microscopic moenteum space optical potential.The results show that the phase leads to differential cross section and polarization are in better agreement with experimental data.
