Ea. Volkova et al., Double-electron ionization of a quantum system in a laser field: Rescattering and interparticle correlations, J EXP TH PH, 91(4), 2000, pp. 706-712
Double-electron ionization of a model two-electron quantum system, describi
ng a one-dimensional negative hydrogen ion, by a high-intensity laser pulse
is investigated by direct numerical integration of the nonstationary Schro
dinger equation. The possibility of interpreting the data obtained on the b
asis of the rescattering concept is analyzed. It is demonstrated that elect
ron-electron correlations play an important role in the description of doub
le-electron ionization phenomena. (C) 2000 MAIK "Nauka/ Interperiodica".
