Luminescence process, refractory stabilities, and new novel electronic states: scanning chemical reactions and novel products for laser induced isotope separation. Progress report, December 1, 1975--July 15, 1976
The formulation, development, and use of versatile oven systems for high temperature metal vaporization at temperatures in excess of 2000/sup 0/C are discussed. Refinements of an apparatus appropriate for the production and study of small metal aggregates M/sub n/(2 less than or equal to n less than or equal to 6) are discussed at length. Improvements in the argon ion and nitrogen pumped dye laser systems, and necessary additions for effective interfacing of these dye lasers to the aggregates apparatus are described. Internal calibration standards are discussed. Progress on the production of carbon vapor and the reaction of this vapor with metal atoms and metal dimers to form metal carbides is outlined. Metal sulfide chemistry is discussed. Several specific studies of the luminescence process are outlined. Included in these studies are completed work on aluminum oxidation. Studies of germanium and silicon oxidation are outlined, and new investigations of inorganic hydride oxidation are presented. The status of our efforts to form new and novel surfaces via aggregate deposition is outlined. Quantum chemical calculations on small metal aggregates are discussed. The first applications of dynamic laser induced fluorescence to the AlO molecule are presented.
