Abstract

Measurement of negative ion mobilities is carried out in O₂ at atmospheric pressure. This high pressure condition gives extremely low electric field intensity compared with the other swarm experiments. In this paper, we describe the results of experimental values of O₂^- mobility in O₂ varying with the drift length from 1.5cm to 9.4cm. The experiments were performed from 0.007 to 4.5V/cm? Torr in reduced electric field intensity. Mobility of O₂^- against the reduced electric field intensity are almost agreed within 3.5cm in drift length. Obtained zero field mobility of O₂^- is 2.13cm²/V•s and this value agree with the values of other researchers. But if the drift length is longer than 3.5cm, the zero field mobility of O₂^- become small with increase the ion drift length. This fact suggests that O₂^- changes to another ion species by ion-molecule collisions during the flight through the drift space.
