Abstract

Ground and excited state energy levels of the Schrodinger equation for various model potentials, in two-dimensional space are calculated, using inner product and renormalized series techniques, over wide ranges of relevant perturbation parameters. Mixed parity potentials are treated, whereas earlier works have treated only even parity perturbations.
