ELECTRON IMPACT DISSOCIATION OF CO2+ TO C+ AND O+ P.Defrance, E.Bahati, H.H.Cherkani and J.Jureta* UCL,Departement de physique, Chemin du cyclotron 2, B-1348 Louvain la Neuve, Belgium *Institute of physics, Belgrade, Yugoslavia Absolute cross sections for electron impact dissociation of CO2+ to the fragment ions C+ and O+ have been measured from the corresponding thresholds to 2500 eV. The C+ has a maximum of 2,8x10(-17) cm(2). The O+ is represented by the two cross section curves with maxima at 1,3x10(-17) cm(2) and 0,5x10(-17) cm(2).
