State and site selectivity in SF6 fragmentation studied via Auger electron-ion coincidence

The fragmentation of sulfur hexafluoride by 4 keV electron impact is studied via Auger electron-ion coincidence experiments in the range of 50 to 70 eV of the binding energy of the dication. Results are presented for the fragmentation following S 2p and F ls ionization. The experimental data confirm that no bound SF2+ 6 states exist at the studied energies and that the fragmentation pattern strongly depends on the dication final state and the site where the primary hole is located
