ABSTRACT: In this paper, an efficient approximate analytical technique for solving the one-dimensional Schrödinger equation (SE) with an attractive Gaussian potential is developed. This technique is based on approximating the Gaussian potential well (GPW) with the modified Pöschl-Teller potential (MPTP), and on the first- and second-order perturbation treatment of the resulting bound state energies and wave functions. In order to illustrate the excellent performance of our technique, we compare our results with those obtained from the exact Hamiltonian diagonalization on a finite-real basis of associated Legendre functions (ALF).
