Hypervirial perturbation calculations for double-well potentials of perturbed oscillator type

Abstract

The renormalized hypervirial perturbation method is used to compute the energy levels for a double-well potential V(x) = −Z2x2 + x2J. Results are produced for a wide range of parameters [Formula: see text] and of state numbers [Formula: see text]. Comparison is made with results obtained by other means.
