Mobilities of Mass-Identified Atomic Ions in the Noble Gases

Abstract

A drift tube/mass spectrometer apparatus has been used to determine the mobilities of mass-identified atomic ions in the noble gases as a function of E/p (drift field/gas pressure) at T = 295 K. The measured values of the reduced mobilities of He(+) in He, Ne(+) in Ne and Ar(+) in Ar are in agreement with earlier investigations and quantal calculations, but the observed decrease of mobility with ion energy is somewhat slower than that predicted by theory. The measured mobility of each of the noble gas ions in He is found to be 6-12% lower than that of the corresponding alkali ion (as determined by Tyndall's group).
