Resumo(s)
We measured the reduced mobilities of the atomic, Ne+, and dimer, Ne2+, ions in Ne, under different pressures and reduced electric fields, at 300 K. Extrapolation to zero field yields values of 4.4 cm2 V-1 s-1 for Ne+ and 6.2 cm2 V-1 s-1 for Ne2+, which are in relative good agreement with other published data. The Ne+ ions are converted to Ne2+ by a three-body reaction with a rate constant that was also measured. Its average value for reduced electric fields in the 8 to 12 Td range was (5.6 ± 0.1) × 10-32 cm6 s-1 at 300 K, also agreeing with the results from other authors using other techniques.
