Thermal Diffusion in Ionized Gases
Proceedings of the Physical Society, 1958Thermal diffusion in mixed gases depends on a `thermal diffusion factor ' α, which is less than unity in all known neutral gas mixtures (in which the particles have no electric charge). In simple ionized gases α exceeds unity, being of order Z+1, where Ze is the charge on the ions. However, in the steady state of such a gas, at non-uniform temperature,

Ionizing Potentials of Multiatomic Gases
Physical Review, 1924Ionizing potentials for helium and fifteen compound inorganic gases were measured by accelerating photo-electrons through a gauze into a chamber where the positive ions produced were drawn to a fine Pt electrode, made small so as to eliminate effects due to radiation.

Conductivity of Slightly Ionized Gases
The Physics of Fluids, 1961A kinetic theory of the conductivity of a slightly ionized gas is developed to distinguish between alternate expressions derived by Desloge et al. from the Boltzmann transport equation. It is determined that the current in a Lorentzian model is obtained by averaging the electron drift velocity over a function resembling the zero field distribution ...

Ionization Measurements in Shocked Gases
1961Previous studies of electrical properties of thermally ionized gases are reviewed briefly, emphasizing the use of microwaves, which is the method employed in the present investigation. The microwave absorption method, developed by W. Low and the author is explained briefly, a short description of the apparatus and calibration procedure following.
