Shake core level satellite spectra

Group IV Metal Sulphides. The core-level electron spectrum of CSg, excited by Mg radiation, has been studied to identify shake-up satellite lines associated with ionizations from these levels. A number of such lines were observed and possible assignments suggested using the excited states of the molecule as a guide. The valence spectra were also recorded and they too were found to be rich in shake-up structure. The photoelectron spectra of... 

Two other types of peaks that can be observed in the XPS spectrum of solid materials are referred to as a shake-up and shake-off satellites. When a core-level electron is ejected from an atom by photoemission, the valence... 

The recent experimental core level spectrum by Cavell and Allison129 in Fig. 50 is very similar to that of N2 (Fig. 45), with a weak Is 3(1 jAr) satellite with 2% relative intensity at 7.2 eV above the main line, a strong 1 s 3(1 n 2 ri) satellite with 10% relative intensity at 12.2 eV, followed by a prominent discrete and continuous satellite spectrum at higher energies. The total relaxation shift is 16 eV, the MO HF ljs level lies well above the low-lying nn satellites and the limited range of the shake-up and shake-off spectrum shown in Fig. 50 only accounts for about one third of the relaxation shift (through Eq. (22)). 

The PS spectrum has a strong peak centered at 285 eV associated with the direct photoionization of the core levels and a low-energy satellite peak at 291.6 eV arising from shake-up transitions ( tt it ) accompanying core ionization. These...
