论文摘要
我们重新审视了对齐的o $ _2 $，co $ _2 $和CS $ _2 $分子的强场电离，这是根据强场物理学领域的最新进展，尤其是在schr {dingere equel equim of schr {dinger} dingse equim newere schr {dingere equect的数值方面中包含多电体偏光范围。在包含多电体极化和TDSE模型中相关诱导的偶极电位后，我们获得了总电离产率的角度分布，这与CO $ _2 $和CS $ _2 $的可用实验结果更好地一致。对于探测的分子，通过在短距离内引入一个磁场来抵消所施加的外部场并导致一定的切割半径内消失的时间相互作用，从而捕获了多电体极化对光电子动量分布（PMD）的主要影响。因此，对于PMD，我们没有发现激光诱导的偶极电位的远距离部分的烙印。
We revisit strong-field ionization of aligned O$_2$, CO$_2$, and CS$_2$ molecules in light of recent advances in the field of strong-field physics, in particular the inclusion of multielectron polarization in the numerical solution of the time-dependent Schr{ö}dinger equation (TDSE) within the singe-active-electron approximation. Upon inclusion of multielectron polarization and the associated induced dipole potential in the TDSE model, we obtain angular distributions of total ionization yields which are in better agreement with the available experimental results for CO$_2$ and CS$_2$. For the probed molecules, the main effect of the multielectron polarization on the photoelectron momentum distributions (PMDs) is captured by the introduction of a field at short distances that counteracts the applied external field and leads to a vanishing time-dependent interaction within a certain cut-off radius. Hence, for the PMDs we find no imprints of the long-range part of the laser-induced dipole potential.
