Abstract
Following a short review of the phenomena leading to changes in the Auger spectral distributions, it is demonstrated how Auger spectroscopy can be used for revealing the electronic structure local to the initial core hole and for obtaining information on hole-hole and electron-electron correlations. Using the Auger parameter concept, by the help of different Auger parameters, the initial and final state effects can be separated, the local screening and ligand polarizability can be characterized and the charge transfer can be determined. The advantages of the use of the X-ray excited Auger spectroscopy and cluster molecular orbital theoretical models in the studies of chemical and solid state effects on Auger processes are discussed. The power of these methods is illustrated by recent results obtained for metals, alloys and oxides, including materials of great practical importance.
