Cross-section analysis and analyzing power for p-3He system via modified phase-amplitude method

As traditional phase function method is no longer a valid tool to calculate phase shifts for scattering involving local plus nonlocal interaction, thus modified phase-amplitude method is adapted to deal with Deng-Fan plus Graz separable potential. The electromagnetic effect is included rigorously to construct a closed-form expression for the scattering phase shifts. The present approach to the problem circumvents in a rather natural way the typical difficulties of incorporating the Coulomb/electromagnetic interaction in a nuclear phase shift calculation. Our approach is demonstrated by calculating the scattering phase shifts and hence differential cross section and proton analyzing power of p-3He system which compare well with existing experimental and theoretical data.
