【 摘 要 】

An experimental investigation of sequential dissociation of CO2by Ne4+ion impact at incident energies 1.12 MeV was performed. Two initial states of (CO2)3+ions were observed in the first fragmentation step. But for the second fragmentation step, our result suggests that both the metastable ions (CO)2+are populated in3Σ+states.
