Abstract: | Studies of the time dependencies of the number density of N 2 + , Ne+ and Ne 2 + ions have been made during the decay period of plasmas produced in neon containing various concentrations of nitrogen molecules. Reaction rate constants were obtained for N 2 + +N2+Ne→N 4 + +Ne((1.2±0.2)×10?29 cm6 sec?1) and Ne++N2→N 2 + + Ne ((2.9±0.3) × 10?12 cm3 sec?1). The ambipolar diffusion coefficient of N 2 + in neon was found to beD a p o =350±20 cm2 sec?1 Torr. |
