This paper presents a study of the effect of an electric field on the electronic structure of diatomic molecular systems, using the variational method. Some new features which appear in the molecular Stark effect are shown with the help of simple examples. A near-degenerate perturbation scheme is proposed to complement, or replace, the conventional perturbation treatment for internuclear

The method is suitable for symbolic computation which enables one to calculate the perturbation corrections exactly. We explicity calculate the Stark shift Resonances in Stark effect and perturbation theory. August is proved that the action of a weak electric field shifts the eigenvalues of the Hydrogen atom into resonances of the Stark effect, It is proved that the action of a weak electric field shifts the eigenvalues of the Hydrogen atom into resonances of the Stark effect, uniquely determined by the perturbation series through the Borel method. This is obtained by combining the Balslev-Combes technique of analytic dilatations with Simon's results on anharmonic oscillators. The Quadratic Stark Effect; Degenerate Perturbation Theory: Distorted 2-D Harmonic Oscillator; The Linear Stark Effect; Contributors and Attributions; If an atom (not necessarily in its ground state) is placed in an external electric field, the energy levels shift, and the wavefunctions are distorted. This is called the Stark effect. 11.5: Quadratic Stark Effect.

We have solved the Hydrogen problem with the following Hamiltonian. Now we want to find the correction to that solution if an Electric field is applied to the atom.

Resonances in Stark Effect and Perturbation Theory. Sandro Graffi1* The Stark effect on a Hydrogen-like atom is described by the Hamiltonian operator: (1.1).

Suppose that a hydrogen atom is subject to a uniform external electric field, of magnitude | E |, directed along the z -axis. The Hamiltonian of the system can be split into two parts.
