    "abstract": "In the triple ionization of the Li ground state by single photon absorption\nthe three electrons escape to the continuum mainly through two collision\nsequences with individual collisions separated by time intervals on the\nattosecond scale. We investigate the traces of these two collision sequences in\nthe classical probability densities. We show that each collision sequence has\ncharacteristic phase space properties which distinguish it from the other.\nClassical probability densities are the closest analog to quantum mechanical\ndensities allowing our results to be directly compared to quantum mechanical\nresults.",
