| Outline of Final Research Achievements |
Non-self-sustained discharge plasma generation with ionization waves with over-voltage pulses has been experimentally studied for efficient vibrational excitation of nitrogen molecule, a key for highly efficient plasma nitrogen fixation. This research demonstrated selective generation of vibrationally excited nitrogen by reduced electric field control at 0.1 atm. Furthermore, generation and observation of highly-excited nitrogen vibrational states up to v = 13 were experimentally achieved.
