ION CONVERSION IN XENON AFTERGLOW PLASMAS

Abstract

Mass‐identified measurements of the time dependence of the density of atomic xenon ions in decaying plasmas are reported. The measurements yield a mobility μ₀(Xe⁺) = 0.66 cm² V⁻¹ sec⁻¹ for Xe⁺ in xenon, and for the rate of conversion of Xe⁺ into ${\mathrm{Xe}}_2^{+},$ a value of 1.8×10⁻³¹ cm⁶ sec⁻¹ at a gas temperature of 300°K.
