Dynamic effect on the structure of X-ray photoelectron spectra of lanthanide fluorides and oxides

Dynamic effect on the fine structure of X-ray photoelectron spectra of lanthanide oxides and fluorides is discussed. The Ln4p electron spectra are considerably complicated by the interaction between the configurations of themain one-hole and additional two-hole final states of 4p54d54fn ↔ 4p64d8fn+1 type. The effect of the nature of atoms in the nearest environment of lanthanide ions on the fine structure parameters is evaluated.
