Dependence of Zero-field Ion Mobilities on Well Depth and Minimum Position in the Ion-Neutral Interaction Potential

Abstract

The dependence, at fixed temperature, of the zero-fielci ion mobility on well depth E and minimum position r m in the ion-neutral interaction potential is explored. For large values of r m the mobility is very sensitive to small changes in E, but at small r m the mobility varies only slightly from the Langevin value.
