Description
RgCl(B,C,D) excimers were produced for Rg = Ar, Kr, and Xe by the positive ion-negative ion recombination reactions of Rg^+(^2P_<1/2,3/2>) with C_6F_5Cl^- in the flowing afterglow. Spin-orbit state selectivity of RgCl(B,C,D) excimers by the Rg^+(^2P_<1/2>) and Rg^+(^2P_<3/2>) components was examined by using appropriate filter gases of one spin-orbit component. The RgCl(B,D) ratio was determined to be 0.35:0.65, 0.05:0.95, and 0.24:0.76 in the Ag^+(^2P_<1/2>), Kr^+(^2P_<1/2>), and Xe^+(^2P_<1/2>) reactions, whereas the RgCl(B,C) ratio was estimated to be 0.74:0.26, 0.71:0.29, and 0.70:0.30 in the Ag^+(^2P_<3/2>), Kr^+(^2P_<3/2>), and Xe^+(^2P_<3/2>) reactions, respectively. The Rg^+(^2P_<1/2>) reactions had a high propensity to give RgCl(D) plus a lesser amount of RgCl(B), whereas the Rg^+(^2P_<3/2>) reactions gave only RgCl(B,C). These results show that Rg^+(^2P_<1/2>) + Cl^- and Rg+(^2P_<3/2>) + Cl- characters are conserved well for the formation of RgCl* in the ion-ion recombination reactions between Rg^+(^2P_<1/2,3/2>) and C_6F_5Cl-. Higher conservation of Rg^+(^2P_<1/2>) character in the Rg^+(^2P_<1/2>)/C_6F_5Cl- reactions than that in the Rg(^3P_0)/halides reactions is discussed by using correlation diagram between entrance and exit product channels.
