STUDY OF COLLISION PROCESSES IN GASEOUS PLASMAS.

Abstract

Results obtained from studying the mobility of ions and the properties of decaying plasmas are summarized. The measuring method consisted of the simultaneous application of pulse techniques and mass and light spectrometer techniques. The plasmas studied were produced in helium, neon, nitrogen, helium-neon mixtures, and helium-nitrogen mixtures. Long existing discrepancies in the explanation of the origin of the afterglow light emission were resolved in helium and neon. Information about electron-ion recombination processes was obtained. The same was possible with respect to the mobility of positive ions in their parent gas. The studies performed on nitrogen afterglows resulted in establishing the production of N2(+) nitrogen afterglows resulted in establishing the production of N2(+) ions by mutual collisions between metastable molecules. A theory and method for determining the catalytic efficiency of a surface for recombination of nitrogen atoms were developed. (Author)
