Abstract
Three potentials, one long range, Kratzer and two short range, Hulthen and Poschl-Teller, were used to investigate the range of validity of the perturbation method developed by Muller-Kiresten.
Eigenvalues obtained exactly for these potentials are compared with those obtained by perturbation methods. These results are discussed in the conclusion
