英文摘要	The ionization and dissociation fractions of the CO2 molecule under the impact of 10-30-keV negative ions H-, C-, and O- are studied. The four recoil ions originating from the target molecule CO2 (CO2+, CO+, O+, and C+) are measured and identified in coincidence with projectiles in two final charge states (q = 0 and q = +1) by using a time-of flight spectrometer. The ionization and dissociation fractions of CO2 are found to associate with the momentum of the impacting ions. We also analyze the fractions for ionization and dissociation from a physical point. No comparison is given since no other experimental and theoretical data exist in the investigated energy range.
