The fragmentation of CCl4 dications studied by Auger electron-ion coincidence experiments

Abstract

The formation and decay of dication states of tetrachloromethane has been studied in an electron impact experiment by Auger electron-ion coincidence measurements. The fragmentation following the Cl2p ionization has been studied in three different binding energy regions of the dication between 33.5 and 48.5 eV. In the experimental data no bound stable or metastable CCl42+ states have been observed and the fragmentation pattern of the dications resulted to be strongly dependent on the state and geometry of the dication.
