DC STRONG-FIELD STARK-EFFECT - CONSISTENT QUANTUM-MECHANICAL APPROACH

The energies and the widths of the Stark resonances for the hydrogen a tom are calculated using a new approach. It is based on the operator f orm of the perturbation theory of the Schrodinger equation. The method includes the physically reasonable distorted-waves approximation in t he frame of the formally exact quantum-mechanical procedure. The zero- order Hamiltonian possessing only stationary states is determined only by its spectrum without specifying its explicit form. The method of c alculation of the perturbation theory matrix elements is described.
