Discrete and continuum quantum states for the Kratzer oscillator

Abstract

Abstract Kratzer oscillator is a realistic zero‐order model for describing the anharmonic ro‐vibrational motion in diatomic molecules. Kratzer oscillator has an energy spectrum containing both discrete and continuum parts. Wavefunctions belonging to the continuum would be useful in the study of transitions to the continuum in molecular dissociation processes. In this article, bound and scattering wavefunctions of the Kratzer oscillator are reviewed and the bound–bound and the bound–free matrix elements are obtained. © 2002 Wiley Periodicals, Inc.
