摘要: We have used a drift tube mass spectrometer to measure the mobilities and longitudinal diffusion coefficients of mass‐identified K+ ions in argon at 300°K. The range E / N extended from 1 610 × 10−17V · cm2, where is electric field intensity number density neutral gas. zero‐field reduced mobility was found be 2.66 ± 0.05 cm2/V sec, close agreement with value previously reported by Tyndall for that were assumed but not identified. low‐field agree well predicted Einstein equation using experimental mobility. Our data are compared theoretical predictions Wannier Whealton Mason, obtained Skullerud lacking spectrometer.
