Abstract

Using three-dimensional classical ensembles, we have investigated the internuclear distance dependence of nonsequential double ionization (NSDI) of H2 molecules by an 800 nm, 1×1014 W/cm2 laser pulse. For the internuclear distance R ranging from 2 to 12 a.u., the NSDI of H2 provides rich correlation patterns in the two-electron momentum distributions. These correlation patterns essentially reveal different microscopic dynamics in NSDI process. Moreover, our calculations show that R ≈ 4 a.u. is the critical distance for double ionization yield of H2. These results are qualitatively explained based on the classical barrier expression model and back analysis.
