- Experimental measurement of the mobilities of atomic, Ne+, and dimer, Ne2+, ions in NePublication . Garcia, A. N. C.; Trindade, A. M. F.; Oliveira, T. D. P.; Neves, P. N. B.; Barata, J. A. S.; Távora, L. M. N.; Dias, T. H. V. T.; Borges, F. I. G. M.; Conde, C. A. N.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. The value obtained for the atomic ion, 4.1 cm2V1 s1, is in good agreement with other values published in the scientific literature. The value obtained for the mobility of the dimer ion, 7.3 cm2 V1 s1, is not in accordance with other published data. We discuss the most probable sources of error.
- Experimental Measurement of the Ne+ and Ne+2 Mobilities in Ne and the Reaction Rate Coefficient for Ne++2Ne→Ne+2+NePublication . Neves, P.N.B.; Garcia, A. N. C.; Trindade, A. M. F.; Barata, J. A. S.; Távora, L. M. N.; Conde, C. A. N.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.
