A new approach is described for obtaining absolute electron-impact cross sections for ionization, including the partial cross sections for multiple charge excitation and ion dissociation. The method benefits from the use of a supersonic molecular beam, pulsed ion source, and multichannel mass detection. The determination of the partial cross sections for the production of Ne+, Ne'+, Ar+, Kr+, and Kr2+ from the neutral atoms, as well as for the production of NH,+, NH;, and NH+ from rovibrationally cold NH,, are reported and compared with results from other recent work.

## Abstract Partial ionization cross section experiments have been carried out recently at the University of Innsbruck for three types of hydrocarbons, i.e. acetylene, ethylene and propene. Cross section data fits are generated and compared to the compilation of earlier experimental data summarized
