Ma-Xu quantization rule and exact WKB condition for translationally shape invariant potentials
arXiv:1001.0495 · doi:10.1016/j.physleta.2010.11.010
Abstract
For translationally shape invariant potentials, the exact quantization rule proposed by Ma and Xu is a direct consequence of exactness of the modified WKB quantization condition proved by Barclay. We propose here a very direct alternative way to calculate the appropriate correction for the whole class of translationally shape invariant potentials.
