Original Abstract

The work presents results obtain during spectroscopic observations of DC flowing post-discharge of pure nitrogen plasma. The total gas pressure was varied from 500 Pa up to 5 000 Pa. The maximum of intensity of pink afterglow phenomenon was observed at decay time 5 ms at 500 Pa and it was moved to the later decay times up to 20 ms with increasing total gas pressure. Relative populations of N2 (B), N2 (C) and N2+ (B) states were calculated from measured intensities. Simplified kinetic model was proposed.
