We have set up a coincidence apparatus consisting of a high-resolution electron spectrometer and a k-resolving ion spectrometer. As an example for measurements performed with this apparatus, we present ion mass spectra that are coincident with energy-resolved resonant Auger electrons emitted from F 1s excited SF6 molecules and resonant Auger electron spectra that are coincident with mass-selected fragment ions, as a function of the detuning from the F(1s-1)a1g* resonance in SF 6. Significant changes of these spectra due to detuning suggest that a substantial fraction of the excess photon energy goes into fragmentation rather than into electron kinetic energy.
