The shifted 1/N expansion and the energy eigenvalues of the Hulthen potential for l not= 0

Abstract

The shifted 1/N expansion has been used to obtain the energy values of the Hulthen potential for non-zero values of the orbital angular momentum. The analytic expression for the energies En,l yield fairly accurate results for a wide range of values of n,l and the screening parameter lambda . The energy values obtained by this method have been compared and found to be in excellent agreement with Pade approximation calculations.
