This review critically evaluates the suitability of Auger spectral line shape analysis as a source of electronic structure information. Methods for extracting the true Auger line shape from the raw data and a theoretical framework for semiquantitative interpretation of that line shape are presented. A wide range of recent applications, concentrating on the line shapes of the low Z metals Be, Li, Na, Mg, and A1, the line shapes of C and Si, the transition metals, and finally those of the metal oxides and halides, are considered. Spectra for gas phase molecules, absorbed molecules, and solids are examined. Finally, new methods for controlling the background, the initial state, the spin polarization, and the angle of escape are discussed , along with requirements for improving the theory. Over 350 references are included.
