Analysis of p-d elastic scattering cross section below the breakup threshold energy through PFM

Phase Function Method (PFM) is an efficient as well as a simplest method for dealing with quantum mechanical scattering problems involving both local and nonlocal interactions. Unlike the local potential, in case of nonlocal potential the accumulation of the phase depends on the wave function for all values of r. Therefore, it is of considerable interest to apply PFM for nonlocal interaction. The modifications in traditional PFM for treating Coulomb/Hulthén distorted separable nonlocal potential have been reported. The electromagnetic effect is to be quite important in low energy scattering demanding rigorous inclusion of the effect in the model. Generally, screened/cut off Coulomb potential is preferably used to represent the electromagnetic part of the charged hadronic systems as the poor asymptotic behavior of pure Coulomb one can affect the calculations of the theoretical results. In this context, the Manning Rosen potential, satisfactorily serves as a model for the molecular as well as nuclear interaction. Here we use Manning-Rosen potential as a short-range electromagnetic interaction adding to nonlocal separable potential in all partial waves for treating p-d elastic scattering thorough modified PFM
