Abstract
Recently there has been much activity on line emission studies from nitrogen plasmas (1-5), primarily due to their relevance in understanding of upper atmospheric emission. But hitherto there has been little experimental work which investigates the nature of quantitative correlation between the population densities of excited states in laboratory ni trogen plasmas and cross sections of relevant electron impact processes. However , such investigations to be amenable to quantitative correlations with atomic processes, values of plasma parameters must directly be known. This is not available from earlier laboratory plasma experiments. Here we report the results of an experiment in which in situ measurements of electron densities (ne) and electron temperatures (Te) were carried out besides vibronic and rotational transition intensities from a ni trogen plasma.
