【 摘 要 】

Electron impact induced three-body fragmentation of CO2q+(q = 3, 4) is investigated. For CO23+, non-sequential and sequential fragmentation processes are observed. For CO4+2, however, only non-sequential fragmentation processes are observed. The momentum correlations of each dissociative channel is analyzed by Newton diagram.
