State and site selectivity in SF_6 fragmentation studied via auger electron-ion coincidence

摘要

The fragmentation of sulfur hexafluoride by 4 keV electron impact is studied via Auger electron-ion coincidence experi- ments 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 1s ionization. The experimental data confirm that no bound SF~2+_6 states exist at the studied energies and tat the Fragmentation pattern strongly depends on the dication final state and the site where the primary hole is located.
