Abstract

A linear model of He was used to study how the distributions of electron and ion momenta, following double ionization, depend on the laser intensity. The calculated distributions showed good agreement with experiment. The results and the analysis of the phase-space motion of the electronic center of mass via the Wigner transform of the two-electron wave function strongly support the rescattering mechanism for nonsequential double ionization in the intermediate intensity regime.
