Electron -Ion Recombination ofXe+and XeH+Ions

Abstract

The properties of ${\mathrm{Xe}}^{+}$ and Xe${\mathrm{H}}^{+}$ ions were studied in xenon and helium-hydrogen-xenon mixtures, respectively, by means of the stationary-afterglow method. The time dependence of the number density of these ions was measured by mass-spectrometric techniques. The temporal behavior of the intensity of the 4671-Å spectral line of xenon was determined by light-spectrometric techniques. The studies established for the first time the occurrence of the collisional recombination process ${\mathrm{Xe}}^{+}+2e\to {\mathrm{Xe}}^{*}+e\to \mathrm{Xe}+e+h\nu$ and that of the dissociative recombination process $\mathrm{Xe}{\mathrm{H}}^{+}+e\to {\mathrm{Xe}}^{*}+\mathrm{H}\to \mathrm{Xe}+\mathrm{H}+h\nu$.
