Abstract

Detailed measurements of the cross-section for non-dissociative ionization of CO2 are presented and compared with available experimental and theoretical results. An excellent agreement is found with the energy dependence of another experimental determination; however, uncertainties exist over the magnitude. Also presented are the preliminary results for the combined cross-section for direct dissociative ionization of CO2 into O+ or C+.
