Perturbation theory; Padé approximants; Killingbeck potential; three-dimensional harmonic oscillator

In this paper we study a certain class of generalized perturbation problem for the isotropic three dimensional harmonic oscillator, forl=0 states only, for all excited states. The efficacy of our formalism is tested by studying the Killingbeck potential in detail. We also briefly present our results using the diagonal Padé approximants.
