Neutron-Proton Scattering Phase Shifts in S-Channel using Phase Function Method for Various Two Term Potentials

The scattering phase shifts for n-p have been modeled using various two term exponential type potentials such as Malfliet-Tjon, Manning-Rosen and Morse to study the in S-channels. As a first step, model arameters each of are determined by obtaining binding energy deuteron matrix methods vis-a-vis Variational Monte-Carlo (VMC) technique minimize percentage error w.r.t. experimental value. Then, order ODE given function method (PFM), is numerically solved 5th Runge-Kutta (RK-5) technique, substituting obtained calculating bound 3S1 channel. Finally, potential parameters varied least squares sense VMC obtain phase-shifts 1S0 values seen be matching with those other analytical techniques comparative analysis up 300 MeV presented.
