title: Argon-like three-electron trajectories in intense-field double and triple ionization.
abstract: We present the double- and triple-ionization momentum distributions obtained from a 3-e planar classical calculation in a laser pulse with peak intensity of 0.8 PW/cm(2). The calculated distributions agree surprisingly well with the experimental Ar(2+) and Ar(3+) distributions at the same laser intensity. We demonstrate four recollision pathways that contribute significantly to the production of the doubly and triply charged ions. In particular, the intense-field double ionization pathways are discussed beyond the two-active-electron picture.
