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

Abstract

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 cm 2V −1sec −1 respectively. The reaction rate coefficient for the termolecular ion-neutral association reaction is (4.6 ± 0.35) × 10 −32 cm 6 sec −1 and in the range from 2 to 10 V cm −1 torr −1 it does not depend on the electric field strength.
