Abstract

We study various short range potentials and calculate their eigenvalues for both s- and p-waves using a wide range of coupling constants. We obtain these eigenvalues, first by perturbation methods, then compare these values with the ones obtained numerically and when it is possible by exact methods. Good agreements are obtained for s-waves eigenvalues and the implications for higher angular momenta eigenvalues are discussed.
