Hypervirial perturbation theory for eigenenergies for two types of atomic potentials
Eigenenergies are calculated for the potentialsV1(r)=−(a/r)[1+(1+br)e−2br] andV2(r)=−(v/r)[1 −λr(1−Z−1)(1+λr)−1], using renormalized series technique. Accurate results produced here for various eigenstates agree with those available in the literature.
