Abstract

We theoretically investigate the mechanism of enhanced ionization in two-electron molecules by analyzing Bohmian trajectories for a one-dimensional H₂ in an intense laser field. We identify both types of ionizing trajectories corresponding to the ejection from the up-field and down-field cores. The trajectories of the two electrons are correlated with each other in the former, while correlation is negligible in the latter. The contributions from the two ionization types, though dependent on laser intensity and internuclear distance, are comparable to each other.
