Abstract
The shifted 1/N expansion has been used for solving the Schrödinger equation for exponential cosine screened Coulomb potential. The analytic expressions for the energies ,l yield fairly accurate results for a wide range of values of n,l and the screening parameter λ. The energy values obtained by this method have been compared and found to be in excellent agreement with the Padé-approximation calculations.
