本文用x射线光电子能谱系统地研究了过渡元素氟化物中3d ~+离子的3s ~+能级。它示出，3s $线的形状是由3d $人口（和随之而来的交换分裂）与不同的核心孔筛选条件。因此，筛选机制被确定为主要贡献者的卫星结构中观察到的核心水平的光电发射。理解这些过程对于解释光电子能谱中的化学效应至关重要。
The cation $3s$ levels in fluorides of $3d$ transition elements have been systematically examined with use of x-ray photoelectron spectroscopy. It is shown that $3s$ line shapes are determined by the $3d$ populations (and consequent exchange splittings) associated with different core-hole screening conditions. The screening mechanisms are thus identified as major contributors to the satellite structures observed in core level photoemission. An understanding of these processes is essential for the interpretation of chemical effects in photoelectron spectra.
