Laboratory Studies of Atomic Collision Processes
Abstract
This research program has dealt with atomic collision processes of interest for models of natural or man made plasmas, such as electrical discharge devices, gas lasers, and atmospheric plasmas. Specific topics have included: Electron ion recombination of NO+, O4+, and N4+ ions, preparation of data compilations on electron ion recombination; Experimental measurements of rates of neutral stabilized electron ion recombination; Experimental measurements of recombination of positive with negative ions; Experimental and theoretical work on ion atom and ion molecule elastic and reactive collisions, and laser-induced charge transfer reactions. Experimental work was carried out on high pressure recombination in helium gas to test theories of neutral stabilized electron ion recombination. A search for effects of electron localization on electron ion recombination in cryogenic helium plasmas at a temperature of 4K has been carried out. Subsequent to the development of suitable experimental methods, ion recombination of molecular ions was studied in helium and argon gas in order to test theories on such processes.
