Abstract

A spectroscopic technique is described to investigate the transport processes of electrons and the quenching processes of excited metastable molecules under the condition of non-self-sustained Townsend discharges. The technique is applied to pure N//2, and N//2 including NO as an impurity at E/N equals 282. 5 Td and currents less than 10** minus **9 A. The results give a quantitative explanation for the rapid decrease of the secondary ionization coefficient in N//2 in the presence of small amounts of the impurity. Also the radiative lifetime and the self-queching rate coefficient are estimated in the present experimental conditions.
