ABSTRACT

Electron-neutral scattering cross sections are important in a number of areas that deal with discharges, plasma chemistry, fusion research, the Boltzmann equation, Monte Carlo simulation, swarm experiments, etc.1 Data on cross sections are one of the most fundamental requirements in the study of gaseous electronics, beginning with the measurements of Ramsauer2 and Brode.3 A large number of measurements were carried out in several gases and a summary of these early investigations is given by Massey and Burhop,4 Bederson and Kieffer,5 Brandsen and McDowell,6 and in the books by McDaniel7 and Hasted.8 More recent compilations of cross section data are published by Trajmar and McKonkey9 and Zecca et al.10
