Production and loss of N2+, Ne+ and Ne2+ during the decay period of plasmas produced in neon-nitrogen mixtures
Studies of the time dependencies of the number density of N2+, Ne+ and Ne2+ 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 N2++N2+Ne→N4++Ne((1.2±0.2)×10−29 cm6 sec−1) and Ne++N2→N2++ Ne ((2.9±0.3) × 10−12 cm3 sec−1). The ambipolar diffusion coefficient of N2+ in neon was found to beDapo=350±20 cm2 sec−1 Torr.
