We numerically investigate the removal of the two outer electrons in the X = He, ${\text{Li}}^{+}$, ${\text{C}}^{4+}$, Be, ${\text{B}}^{+}$ and ${\text{Ne}}^{6+}$ targets by the absorption of a single photon of energy in the extreme UV/soft X-ray spectral region. Our theoretical method to describe the behavior of the electrons in the presence of the laser field is based on a spectral approach of configuration interaction type to solve the time-dependent Schrödinger equation. The probe of the electron dynamics in the different systems shows that the way the outer electrons will leave their parent X system is systematically dictated by the amount of excess photon energy available to them relative to the ionization potential of the corresponding $X^{+}$ ion.

我们用数值方法研究了X = He中两个外部电子的去除，${\text{里}}^{+}$， ${\text{C}}^{4+}$， 是， ${\text{乙}}^{+}$ 和 ${\text{NE}}^{6+}$通过在极端的UV /软X射线光谱区域吸收单个光子能量来达到目标​​。我们描述电子在激光场存在下的行为的理论方法是基于构型相互作用类型的光谱方法来求解与时间有关的Schrödinger方程。对不同系统中电子动力学的探究表明，外部电子离开其母体X系统的方式是系统地由相对于相应电子的电离势可利用的过量光子能量来决定的。$X^{+}$ 离子。
