Mobility of mass-identified ions in neon and reaction rate coefficient for Ne+ + 2Ne → Ne+2 + Ne

The mobilities of mass-identified Ne⁺ and Ne⁺₂ ions in neon have been measured by the “four-gauze” electrical shutter method at 300°K. The reduced zero-field mobilities of Ne⁺ and Ne⁺₂ ions, corrected to 273°K, are 4.13± 0.04 and 6.20± 0.07 cm²V^?1sec^?1 respectively. The reaction rate coefficient for the termolecular ion-neutral association reaction is (4.6 ± 0.35) × 10^?32 cm⁶ sec^?1 and in the range from 2 to 10 V cm^?1 torr^?1 it does not depend on the electric field strength.
