The Discrete Variational Xα-Method Interpretation of the C KVV and Ti L2,3M2,3V Auger Spectra of TiC

The C KVV and Ti L2,3M2,3V Auger spectra are obtained for near stoichiometric TiC. Their interpretation is based on the results of the DVM-Xα calculations of the Auger transition energies in a cluster approach and the evaluation of each transition intensity in the one-centre approximation. The crystal structure is accounted for in the embedding cluster model. Theoretical values of the Auger energies and probabilities of transitions allow to describe qualitatively all the peculiarities of the TiC experimental spectra. [Russian Text Ignored].
