Abstract
The present study is a first attempt to determine electron impact ionization efficiencies for C 2 and C 3. A novel method has been applied to obtain the partial cross-section values for the reactions C 2+e→C +,C 2+e→C 2 + and C 3+e→C +,C 3+e→C 2 + and C 3+e→C 3 +. The neutral target consisting of C, C 2 and C 3 is produced by thermal evaporation from a heated graphite sample and the neutral precursors in the subsequent ionization process can be distinguished by their different flight-time distributions acquired in the evaporation process. The partial ionization cross-section ratios obtained in this experiment have been calibrated with calculated absolute total ionization cross section curves of C 2 and C 3 using the Deutsch-Märk (DM) formalism.
