Radiative Auger effect (RAE) is an effect associated with characteristic 
X-ray emission from an atom.  RAE is the shake-up or shake-off process at 
the electron transition from an outer shell to an inner shell, and is an 
energy loss process in X-ray emission spectra.  Theoretical background of 
RAE as a novel tool to measure the X-ray absorption fine structure of 
condensed systems is presented.
