Study of Kinetic Processes in Nitrogen Flowing Post-Discharge Containing Mercury Traces

Other unclassified results

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 kinetic explanation of the mercury line excitation is based on the resonance energy transfer from the nitrogen metastable level N2 (X1Sigmag+, v = 19) to mercury atom. The rate coefficient of this reaction can be calculated from time dependencies of mercury spectral line intensities, but measurement uncertainty must be taken into account. The rate coefficient value was calculated to be in 10-22 m3s-1 order.
