Perturbation theory for particle in one-dimensional, central- or axial-symmetric fields
Yu. I. Polyakov Sofia University St. Kliment Ohridski
Abstract:
Perturbation theory for which all corrections to a nonperturbed state are defined by its wave function is obtained. A new applicability condition for this theory is formulated. By considering a simple example comparison with the Rayleigh–Schrödinger perturbation theory giving an analytical expression for the corresponding series is performed.
