Interatomic Auger decay in CO molecule

Energy spectra of electrons ejected in electron impact on CO molecules have been measured for the incident electron energy 1400 eV. The aim was to study the interatomic Auger transitions resulted from the filling in the O K-shell hole by a C K-shell electron. The corresponding peaks have been identified and their relative transition probabilities (partial widths) measured. Theoretical widths of these transitions calculated in the Hartree-Fock approximation are in good agreement with the experimental data.
