在三重电离的Li基态的单光子吸收的三个电子逃逸到连续主要通过两个碰撞序列与单独的碰撞分离的时间间隔上的阿秒尺度。我们研究了这两个碰撞序列在经典概率密度中的轨迹。我们发现，每个碰撞序列具有特征相空间属性，区分它从其他。经典概率密度是最接近量子力学密度的模拟，使我们的结果可以直接与量子力学的结果进行比较。
In the triple ionization of the Li ground state by single photon absorption the three electrons escape to the continuum mainly through two collision sequences with individual collisions separated by time intervals on the attosecond scale. We investigate the traces of these two collision sequences in the classical probability densities. We show that each collision sequence has characteristic phase space properties which distinguish it from the other. Classical probability densities are the closest analog to quantum mechanical densities allowing our results to be directly compared to quantum mechanical results.
