Ion Motion in Gases, A Colloquium in Honor of Dr. Ian Gatland

Ion Motion in Gases, A Colloquium in Honor of Dr. Ian Gatland

The history of drift-tube measurements of gaseous ion transport coefficients is reviewed, with an emphases on the contributions made by Dr. Gatland.  The use of experimental measurements of such coefficients in testing ion-neutral interaction potentials over wide ranges of internuclear separation is illustrated through recent tests of ab initio potentials.  Finally, the use of such data with recent theoretical advances is shown to have implications for ion-neutral reactions of importance in the ionosphere.
