✦ Synopsis

Comparison of the high-resolution C ls electron-yield spectrum of CH3F with that of CH 4 reveals that the trc_ F state manifests in a broad and strong feature below the 3s Rydberg band and all the other features are nearly the same as in CH 4. This is supported by improved virtual orbital calculations using the relaxed core-hole potential and avoiding spurious mixing between Rydberg and valence states. In the resonance Auger electron spectra the participant Auger decay rate following the cry_ r excitation, --15%, is much larger than that of the Rydberg excitations, 1-5%.
