Abstract

This article includes discussion about position-dependent mass and quasi-Morse potential. Schrödinger equation in position-dependent mass formalism is considered then Morse potential in terms of mean variable is added into this equation that is why we call it quasi-Morse potential. Then eigenfunctions and eigenvalues are obtained furthermore some discussion about information entropies are discussed using eigenfunctions of the considered system. In order to present better form of our results for each result, we have plotted some figures which can illustrate them.
