“…As discussed by Spicer (1978) and Codling (1979) valence-band XPS spectra can be strongly influenced by atomic effects and with a synchrotron source it is possible to take advantage of one aspect of this: the difference in the energy dependence of the photoelectron cross sections of different orbitals, to deduce the orbital character of different contributions to the DOS. The Te [5p] level, for example, has a Cooper minimum at -30 eV and consequently the valence band of MoTez excited with photons of this energy shows the contribution from the MO [4d] levels (McGovern and Williams 1976). This technique has proved useful in establishing the positions of the anion and cation valence bands of transition-metal oxides.…”

This article reviews developments in the understanding of x-ray-excited Auger and photoelectron spectra in the light of theoretical developments in atomic, molecular and solid-state physics. After reviewing progress in XPS and AES separately emphasis is placed on the inter-relationship between the two fields: Auger rates, for example, are the dominant contribution to core-level XPS linewidths and by combining XPS and AES it is possible to deduce information about Coster-Kronig processes which are difficult to study directly.An account is given of how the combination of measurements of environmentally dependent shifts in XPS and AES energies allows one to isolate intial-and final-state contributions which can then be related to the results of other experimental techniques.There is a brief discussion of many-electron effects which, in some instances, dominate both XPS and AES spectra.Finally we discuss how the combination of XPS and AES spectra involving valence levels enables one to study the effects of hole-state localisation.

Atomic and Molecular Effects in the Vuv Spectra of Solids

The VUV spectra of solids are often dominated by, atomic or molecular effects, which clearly manifest themselves in the gross features of the spectra and the fine structure at inner shell excitation thresholds. Evidence for the influence of atomic and molecular matrix elements, multiplet-splitting and correlation is presented. Special emphasis is given to the direct experimental verification based on the comparison of atomic and solid state spectra
