摘要：

The recombination of deuterated trihydrogen cations with electrons has been studied in afterglow plasmas containing mixtures of helium, argon, hydrogen and deuterium. By monitoring the fractional abundances of H-3(+), H2D+, HD2+ and D-3(+) as a function of the [D-2]/[H-2] ratio using infrared absorption observed in a cavity ring down absorption spectrometer (CRDS), it was possible to deduce effective recombination rate coefficients for H2D+ and HD2+ ions at a temperature of 80 K. From pressure dependences of the measured effective recombination rate coefficients the binary and the ternary recombination rate coefficients for both ions have been determined. The inferred binary and ternary recombination rate coefficients are: alpha(binH2D)(80 K) = (7.1 +/- 4.2) x 10(-8) cm(3) s(-1), alpha(binHD2) (80 K) = (8.7 +/- 2.5) x 10(-8) cm(3) s(-1), K-H2D(80 K) = (1.1 +/- 0.6) x 10(-25) cm(6) s(-1) and K-HD2 (80 K) = (1.5 +/- 0.4) x 10(-25) cm(6) s(-1).
