Abstract : A laboratory study of the generation and recombination of atoms is presented. The background information consists of a discussion of various methods for producing atoms of nitrogen, oxygen and hydrogen by electrical discharges, with primary emphasis placed on the use of intense microwave electric fields. The body of the report deals with the results of investigations into the various loss mechanisms and reactions which affect the experimental use of atoms. These losses are of three types: (a) volume recombination in the bulk of the gas; (b) surface recombinations; and (c) electronic processes in the volume of the gas. Of particular interest is the value of the surface recombination coefficients for nitrogen atoms on various substances. Measurements have been made on Pyrex glass, clear fused quartz, and Alumina and Zirconia ceramics. In addition, the ratio of the number density of the atoms to that of the electrons has been studied as a function of high level radio frequency energy input. (Author)
