摘要: The outer valence electron momentum distributions of benzene are reinvestigated with theoretical calculations involving the vibrational effects. The results are compared with recent experimental measurements [Phys. Rev. A 98 042705 (2018)]. The significant discrepancies between theories and experiments in previous works have now been interpreted quantitatively, indicating that the vibrational motion in benzene molecule has noticeable influence on its electron momentum distributions.
