Phase-shifts determination for nucleon-nucleon scattering using velocity-dependent potentials

The S-wave time-independent Schrödinger equation with an isotropic velocity-dependent potential is considered .We have used perturbation theory to calculate the scattering phase shifts when the energy is changed by a small amount ΔE from an arbitrary unperturbed value E0. The validity of our results were tested by comparing the perturbed phase shifts to those obtained exactly by solving Schrödinger equation. We assumed the local potential to have the form of a finite square well and the velocity dependent part of the potential to have the form of a Yukawa potential.The accepted manuscript in pdf format is listed with the files at the bottom of this page.
