✦ Synopsis

A renormalized hypervirial Pad6 scheme is shown to yield correct energy values for cubic-quartic oscillators only if the quartic term is treated to be of higher order in perturbation than the cubic term. Furthermore, the applicability of the technique to octic anharmonic oscillators, even-power polynomial potentials and to self-interacting oscillators has been studied.
