Abstract: The possibility of measuring high-resolution Auger core-level spectra produced from the ionization of deep levels has recently stimulated interest in their properties. Of special interest are those properties involving the purely atomic and the satellite spectra: the former permits evaluation of theories of atomic spectra and the latter allows study of excited states. Most such studies have treated the L2,3M4,5M4,5 spectra of the 4d metals: theoretical characterization of the atomic portion of the spectra facilitated separation of the satellite spectra and study of their systematics. Reports of other such spectra in the literature are sparse. In this study we present high-resolution L2,3M2,3M2,3 and L2,3M2,3M4,5 Auger spectra measured for Ag, In, Sn, and Sb, and compare them with the results of nonrelativistic atomic calculations of the multiplet structure intensities using a model for closed shells with the initial state treated in the jj coupling scheme and the final state in the intermediate coupling scheme. Comparison of the theoretical results and experimental spectra shows a high degree of agreement for the L2,3M2,3M4,5 spectra. Consideration of the L2,3M2,3M2,3 spectra would seem to indicate the presence of many-body effects. [S0163-1829(99)10147-4].
