Experimental and theoretical free-atom metal shifts have been determined for the M4,5N4,5N4,5 Auger spectra of elements from Ag47 to Te52. The experimental shift values have been obtained either from direct measurement of free-atom metal shifts (Ag,Cd), from measurement of molecular-vapor metal shifts (Sb,Te) combined with semiempirically calculated free-atom Auger energies, or from comparison between calculated or measured atomic and separately measured solid-state Auger spectra (In,Sn). It is found that the free-atom metal shifts remain almost constant through these elements in contradiction to most earlier theoretical predictions. The thermochemical model has been applied to calculate free-atom metal shifts in the Auger spectra, and good agreement with experiment is found. The theoretical shift values have also been calculated using the self-consistent-field density-functional formalism and the results are found to agree very well with the experiment.
