Excitation of Oxygen Atoms by Electrons,

Abstract

An electron beam suitable for excitation function measurement could not be produced by electronic breakdown of the oxygen gas. Adequate electronic breakdown of the gas (a continuous glow rather than a spark type discharge) occured only at pressures above 50 microns. It was not possible to obtain a continuous or glow discharge at pressures below 50 microns. The limitation to pressures above 50 microns prevented formation of a beam from the available electrons because of the short electron mean free path at these pressures. (Author)
