我们介绍了多组态含时Hartree-Fock（MCTDHF）方法，并讨论了显着差异的含时密度泛函理论。该方法适用于电离的一维模型分子与多达八个活跃的电子。相关性显着影响基态电子密度和电离产率。与预期一致，对于恒定的电离势，我们发现电离产率随分子尺寸的增加而增加。
We introduce the multiconfiguration time-dependent Hartree-Fock (MCTDHF) method and discuss significant differences to time-dependent density functional theory. The method is applied to the ionization of one-dimensional model molecules with up to eight active electrons. Correlation significantly influences both ground-state electron densities and ionization yields. In accordance with expectations, for constant ionization potential we find an increase of ionization yields with molecular size.
