Radiative Auger transitions and their consideration in deconvolution of energy dispersive x‐ray spectra

The significance of Auger transitions as spectral components in energy dispersive x‐ray fluorescence spectra is demonstrated. As a summary of fundamental studies on radiative Auger effects the calculation of their energies and relative intensities is demonstrated. These theoretical deductions result in a suitable incorporation in least‐squares techniques by coupling the Auger transitions to the corresponding photopeak originating from the same type of primary vacancy as a function of energy. The simplifications involved, and the removal of systematic misinterpretations and of high correlations of model parameters, are discussed.
