    LIF study of N2(A3+u, v=0-10) vibrational kinetics under nitrogen streamer conditions

  • Original language description

    The evolution of individual v = 0?10 vibrational levels of N2(A3+u )metastable species produced by filamentary streamer discharge was investigated by the laser-induced fluorescence technique.Triggered single streamer filament was periodically produced inpure nitrogen at a pressure of 200 torr and metastable species were monitored during the streamer channel decay in the centre of the discharge gap.The observed dynamics of N2(A3+u) vibrational levels follow two very different scenarios: while higher (v> 6) vibronic levels decay exponentially in hundreds of nanoseconds,the populations of lower levels (v 6) definitely increase,first reaching a local maximum on a microsecond timescale and then decreasing afterwards. Population maxima of N2(A3+u ,v 6) levels occur after the streamer onset with a certain delay, which decreases with increasing vibrational number.Interpretation of experimental observation based on a 0D kinetic model of the post-discharge period takes into account
