Electron-transfer and dissociation cross sections of 1.25- to 25-keVH+,H0,H−, andH2+in collisions with Xe

Abstract

Total collision cross-section measurements of 1.25- to 25-keV ${\mathrm{H}}^{+}$, ${\mathrm{H}}^0$, ${\mathrm{H}}^{-}$ and $\mathrm{H}_2^{}{}_{}{}^{+}$ in Xe are reported for the nine processes ${\mathrm{H}}^{+}$ ⇆ ${\mathrm{H}}^0$, ${\mathrm{H}}^{+}$ ⇆ ${\mathrm{H}}^{-}$, ${\mathrm{H}}^0$ ⇆ ${\mathrm{H}}^{-}$, and $\mathrm{H}_2^{}{}_{}{}^{+}$ → [${\mathrm{H}}^{+}$, ${\mathrm{H}}^{-}$, ($\mathrm{H}_2^{}{}_{}{}^0$ and ${\mathrm{H}}^0$)]. Single- and double-electron-stripping cross sections for which the Xe atom does not change charge are deduced by combining present and past results. Comparisons are made with available experimental data and with theoretical values.
