Abstract
The influence of the photon bandwidth on the line shapes of the resonant Auger electron spectra has been studied. The observed features have been explained as due to the Auger resonant Raman effect, which has been extended to cover the cases of nonmonochromatic excitation. Changes in the line shapes and also several specific effects, connected with detuned excitation, have been demonstrated by experimental examples, matched with model calculations. The lifetime interference phenomenon, appearing in the decay of several close-lying resonance states to the same final state, is regarded together with the influence of the limited photon bandwidth. Special attention is paid to the problems of data handling. \textcopyright{} 1996 The American Physical Society.
