In this study a detailed investigation of the high-energy satellites of the L2,3 Auger emission bands of Al, Si, and P was made. The satellites are interpreted as arising from double ionization of the L2,3 shell rather than from a plasmon gain process. The parent-to-satellite energy separations ΔE between like structures were determined and were found to be consistently smaller than the volume-plasmon energies measured for the same samples. A comparison of Si and SiO revealed no evidence that ΔE for Si is dependent on the volume-plasmon energy of the sample. The satellite threshold excitation energies Et were determined and were found to compare well with results expected for double ionization of the L2,3 level. In the energy range Et
