The resonant Auger effect

A brief survey of the resonant Raman Auger effect is presented. An outline of experimental considerations and equipment is given. The theory of the resonant Auger effect is outlined within the context of a resonant photoionization process, which we hope will provide new researchers in the field a simplified feel for the physics involved. Our focus is on the atomic problem, but we include the connection to the molecular case with some accompanying discussion. Within this context we then discuss some examples which address a number of issues we feel are central to the subject: coherence between intermediate states, the treatment and meaning of correlation effects, the relation to the normal Auger effect, and the experimental complications due to incident-photon bandpass effects.
