THE STUDY OF IONIC PROCESSES IN GASEOUS AFTERGLOWS.

Abstract

The report is concerned with measurements of the decay of the densities of ion species in the afterglows following pulsed radiofrequency discharges in atmospheric gases, in order to determine the reaction rates at thermal energies between various ions and neutral species. The following reactions have been investigated: (1) The decay of the helium ion density in pure helium afterglows and the subsequent deduction of the ambipolar diffusion coefficient of the helium ion in helium gas molecules; (2) The charge exchange rates of the oxygen ion with oxygen and nitrogen molecules; (3) The charge exchange rates of the helium ion with oxygen and nitrogen molecules; (4) The decay rate of the nitrogen ion in pure nitrogen gas preliminary to charge exchange rate measurements between the nitrogen and casesium vapour.
