Mobilities of Mercury Ions in Helium, Neon, and Argon

Abstract

The mobilities of mercury ions in helium, neon, and argon have been measured at 300°K. The values obtained are ${\mu }_0=19.6\left(\mathrm{He}\right), 5.95 \left(\mathrm{Ne}\right), \mathrm{and} 1.84 \left(\mathrm{A}\right)$ ${\mathrm{cm}}^2$/volt-sec. These values are in agreement with extrapolations of the mobility versus mass-number curves obtained for alkali ions in the noble gases by Tyndall and collaborators. The experimental values for ${\mathrm{Hg}}^{+}$ are compared with the Langevin theory in the polarization limit. Good agreement is obtained only for the case of argon.
