## Abstract In this paper a multireference constant denominator perturbation theory (CDPT) is developed to reduce incomplete basis set errors arising when solving the Schrödinger equation with a finite basis set. The advantage of this method is that very few basis functions are needed, and all calc
The Rayleigh Schro dinger perturbation series for the energy eigenvalue of an anharmonic oscillator defined by the Hamiltonian H (m) (;)=p^2 +x^2+;x^2 m with m=2, 3, 4, .. . diverges quite strongly for every ;{0 and has to summed to produce numerically useful results. However, a divergent weak coupl
