Fragmentation of the SF6 molecule upon F 1s excitation has been studied by resonant photoemission. The F atomiclike Auger line exhibits the characteristic Doppler profile that depends on the direction of the photoelectron momentum relative to the polarization vector of the radiation as well as on the photon energy. The measured Doppler profiles are analyzed by the model simulation that takes account of the anisotropy of the Auger emission in the molecular frame. The Auger anisotropy extracted from the data decreases with an increase in the F-SF5 internuclear distance.
通过共振光发射研究了F 1s激发下SF6分子的碎片化。类F原子俄歇线呈现出特征性的多普勒分布，该分布取决于光电子动量相对于辐射偏振矢量的方向以及光子能量。通过考虑分子框架中俄歇发射各向异性的模型模拟来分析测量到的多普勒分布。从数据中提取的俄歇各向异性随着F-SF5核间距的增加而减小。
