Abstract

Double-electron ionization of a model two-electron quantum system, describing a one-dimensional negative hydrogen ion, by a high-intensity laser pulse is investigated by direct numerical integration of the non-stationary Schrödinger equation. The possibility of interpreting the data obtained on the basis of the rescattering concept is analyzed. It is demonstrated that electron-electron correlations play an important role in the description of double-electron ionization phenomena.
