The distorted wave approximation for tan ?l involves a wave function distorted from its asymptotic form at r � 8 by a form factor g1(r). Schwinger's variational principle is adapted to show that increasing the number of variable parameters in g1(r) does not necessarily improve the firs

Scattering Phase Shifts

<p>By judicious exploitation of supersymmetry formalism of quantum mechanics higher partial wave nucleon-nucleon potentials are generated from its ground state interactions. The nuclear Hulthen potential and the corresponding ground state wave function with the parameters of Arnold and MacKellar are used as the starting point of our calculation. We compute the scattering phase shifts for our constructed potentials through Phase Function Method to examine the merit of our approach to the problem.</p>
