1/N expansion for the Yukawa potential revisited: II

Abstract

Using the form prescribed by Moreno and Zepeda for the N-dimensional Yukawa potential and employing the method of 1/N expansion we have obtained in a recent paper the energies of the ground state and the first excited state of a three-dimensional Yukawa potential. In the present addendum we introduce a modified prescription for the N-dimensional Yukawa potential which enables us also to calculate the energies of the higher angular momentum states. Our results are in very good agreement with the accurate numerical values.
