Self-consistent-field wave functions and energies have been used to obtain an interpretation of the KLL Auger spectra of CH4. The computed Auger energies are in good agreement with observed values. The multiplet structure and splittings of the final states of CH4+2 are shown to play a key role in determining the spectra. For the first time, symmetry assignments have been made for the final states of the Auger transition peaks in a molecule. © 1975 The American Physical Society.
