    • Abstract

       

      The perturbation technique for large coupling constantsg2 is used for obtaining the solutions of Schrödinger equation for a double exponential potential. In particular the solution valid forg2e-r/2 g2e-r/2 ≫ 1, is obtained int erms of confluent hypergeometric functions. A noteworthy aspect of this application is that the procedure developed can also be used for solving certain singular potentials.
