Abstract
A new approach to non-relativistic large order perturbation theory for constructing energy and wave function correction up to Kth order has been developed. Convergent argument of this series has been demonstrat ed for the ground state of second order and fourth order Schroedinger equation. Further a comparison with the Bender and Wu computational wo rk reflects that the present series is not the same as Rayleigh-Schroe dinger perturbation series.
