摘要

We report an experimental investigation of ionization dissociation of CO^2+induced by electron impact at incident energy of 380 eV.The fragment ions(C^+/O^+)and the emitted electron were measured in coincidence by utilizing COLTRIMS technique.The kinetic-energy-release(KER)of the fragment ions and the energy of the outgoing electrons are obtained.Based on the characters of the KER distribution and the energy spectrum of the emitted Fig.1(color online)Two-dimensional diagram of the kinetic energy of one of the emitted electrons(vertical)versus the KER of the ionic fragments(horizontal).electrons(see Fig.1),the direct and indirect double ionization((e,3e))including an auto-ionization process were identified respectively.
