The NSDI process is investigated using carrier-envelope-phase-tagged electron-ion coincidence spectroscopy. The measured NSDI spectra of N[subscript 2] and Ar exhibit a striking resemblance. In particular, the correlated two-electron momentum distribution arising from NSDI of N[subscript 2] also displays a cross-shape very similar to that reported for Ar [ Bergues et al. Nat. Commun. 3 813 (2012)]. We interpret our results in terms of recollision-excitation with subcycle depletion and discuss how this mechanism accounts for the observed similarities and differences in the ionization behavior of the two species.en-USThis Item is protected by copyright and/or related rights.
