Experimental investigation of the chemistry of excited states of rare gases. Technical progress report, October 15, 1975--July 15, 1976. [Quenching rate constants and branching ratios for rare gas halide excimer formation]
Total quenching rate constants and branching ratios for rare gas halide excimer formation have been measured for Ar(/sup 3/P/sub 0/,/sub 2/), Kr(/sup 3/P/sub 2/) and Xe(/sup 3/P/sub 2/) reacting with chlorine and fluorine-containing molecules. Emphasis was focused on systems giving KrF* and XeF* as products. All halogen containing molecules quench metastable rare gas atoms with gas kinetic cross-sections. However, only diatomic halogens and small molecules with O-X or N-X bonds quench the metastable with high branching ratios for excimer formation. The product channels for the reagents which do not yield the rare gas halides as the main exit channel remain to be identified. The work that has been done provides a good survey of halogen donors. This work will assist in selection of the best halogen-containing molecules for use in rare gas halide excimer lasers. Tunable dye laser fluorescence experiments have been done to obtain radiative lifetimes and two body quenching rate constants (with ground state Ar) for excited states of Ar*(3p/sup 5/,4p) and Ar*(3p/sup 5/,5p).
