Abstract
The temperature dependence of the electron-ion dissociative recombination (DR) rate of neon dimer ions has been measured in mixtures of helium and neon using the shock tube technique. The temperature range 500-3000 K was examined and the temperature dependence of the observed recombination was found to be independent of the composition of the helium-neon mixture and the different dimer ion formation mechanisms involved. The results obtained confirm earlier arguments about the fall-off in efficiency of DR for vibrationally excited rare-gas ions.
