Features of the Formation of Cluster Compounds in Metal Solid Solutions
Physical origins of the chemical (energy) shifting of Auger electron lines in the spectra of Al–Li, Ba (by 1.4 eV) and Mg–Ba (by 2 eV) systems containing cluster-forming alloying elements such as barium have been discussed. The observed peaks are associated with the formation of Al18Ba9 and Mg16Ba2 cluster compounds characterized by their own electron configurations.
