説明
The positive ion¬negative ion reactions of Kr^+(^<2>P_<1/2,3/2>) The positive ion-negative ion reactions of Kr^+(2P1/2,3/2) with C_6F_5Cl^-, and Xe+(2P1/2,3/2) with SF_6-, C_6F_6^-, and C_6F_5Cl^- have been spectroscopically studied in the He flowing afterglow. KrCl* excimer and excited Kr* atoms were produced in the Kr^+/C_6F_5Cl^- reaction, whereas XeF*, Xe*, and XeCl* and Xe* were formed in the Xe^+/SF_6-, Xe^+/C_6F_6-, and Xe^+/C_6F_5Cl^- reactions, respectively. The branching ratios between recombination and neutralization reactions leading to RgX* (Rg = Kr, Xe, X = F, Cl) excimers and excited Rg* atoms, respectively, were found to be 0.69:0.31 for the Kr^+/C_6F_5Cl^- reaction and 1.00:0.00, 0.00:1.00, and 0.89:0.11, for the Xe^+/SF_6^-, Xe^+/C_6F_6^-, and Xe^+/C_6F_5Cl^- reactions. These results suggested that the branching ratio between recombination and neutralization reactions depends strongly on the negative ion. It was concluded that dissociation energies of target anions leading to X^- and electron affinities of target molecules play a significant role in the ion-ion recombination and neutralization reactions of Rg^+ with SF_6^-, C_6F_6^-, and C_6F_5Cl^-.
