Abstract

The processes responsible for the anomalous edge behavior in the x-ray band spectra of metals are found to play important roles in modifying the intensity of $\mathrm{CVV}$ Auger-electron emission spectra. The dynamical effects related to the sudden switching of the core-hole potential are known to produce a power-law behavior in the neighborhood of the upper emission edge. Using simplified diagrams and a realistic pseudopotential for the core-hole interaction, we have extended the edge theory to energies well below the Auger emission edge. A significant shift in the position of the maximum of the ${L}_{23}\mathrm{VV}$ Auger emission intensity of Al is calculated.
