Measurements of thermal-energy ion-neutral reaction rate coefficients for rare-gas ions

Abstract
A steady-state flowing afterglow method has been used to measure rate coefficients for ion-neutral reactions involving rare-gas ions. In particular the technique has been extended to reactions with neon ions. The rate coefficients are for collisions of He+ with N2, O2, CO2, CO, NO, H2, Ar, Kr, Xe, NH3 and CH4; Ar+ with NH3 and CH4 and Ne+ with O2. The method of analysis of the experimental data is given in some detail.
