Analytic solution of the Schrodinger equation for H-like ions in strong laser fields treating the Coulomb potential exactly: the change of the ionization exponent beyond Keldysh-type theories

Abstract

Taking into account the Coulomb potential comes to a non-Keldysh mechanism of the ejection of photoelectrons from H-like atoms and ions. This new mechanism is responsible for a change of the ionization exponent in comparison with its value predicted by Keldysh's type theory. The analytic treatment of this new phenomenon is presented.
