The ratios of single, double, and triple ionizations to the total photoionization of the halothane (CHBrClF) molecule have been investigated by a single-photon ionization in the energy range from 21.21 eV to 320 eV. In the valence region, the multiple ionization results can be described by a sum of contributions generated from the shake-off and the two-step one models. At low photon energies (from the threshold of triple ionization up to 100 eV), the triple photoionization dynamics of halothane can be reasonably well described by a model involving a classical electron impact double ionization of the singly ionized parent ion.
已经通过能量范围从 21.21 eV 到 320 eV 的单光子电离研究了卤代烷（CHBrClF）分子中单、双和三电离与总光致电离的比值。在价区，多电离结果可以用来自于逐出和两步一模型的贡献之和来描述。在低光子能量（从三重电离的阈值到 100 eV），卤代烷的三重光致电离动力学可以通过涉及单电离母体离子的经典电子碰撞双电离的模型来合理地很好地描述。
