Original Abstract

The DC flowing post-discharge was created in Quartz tube at the nitrogen pressure of 1000 Pa and discharge current of 100 mA. The mercury vapour was added in the flowing afterglow behind the active discharge and the optical emission spectroscopy was performed. Nitrogen 1st positive, 2nd positive and 1st negative spectral systems and mercury spectral line at 254 nm (in the spectrum of second order) were identified. The results showed dependence of mercury spectral line intensity on the decay time. The rate coefficient of the reaction between nitrogen metastable and excited mercury atom can be calculated from time dependencies of mercury spectral line intensities.
