“…Such a method measures both the relative times of the electron ejections and also the relative direction of ejection. The interpretation of the observed two-electron momentum distributions requires extensive knowledge of the trajectory of the electrons and the influence of the laser pulse beyond ionization but also knowledge of the initial momenta of the electrons and the influence of the laser before ionization . It has been shown that an electric field (typically 0.01–0.1 au) present in strong-field approaches may influence the momentum distribution of a single active electron and needs to be considered .…”

The relative momentum of electron pairs in atoms and small molecules is examined through calculation of the p · p probability distribution. The likelihood of aligned or antialigned momenta between paired electrons is determined from the calculated distributions. Coulomb correlation aligns the momenta of electron pairs, and the amount of alignment varies when considering momenta in specific directions in three-dimensional space. A static electric field is found to have competing effects on momentum alignment parallel and perpendicular to the electric field. However, the net effect of the electric field on alignment is significantly smaller than the effect of Coulomb correlation. Recent experimental advances suggest that such a correlation of electron momenta can now be measured directly using attosecond spectroscopic tools.
