Abstract
The role of vibrational excitation in affecting the dissociation under discharge conditions characterized by reduced electric field E/N⩽80Td has been investigated in N2. The kinetic calculations have been performed using a self-consistent approach, solving at the same time the master equation for the composition and the distribution of internal states (vibrational and electronic) and the Boltzmann equation for the electron energy distribution function. The results show that vibrational mechanisms involving heavy particle excited states dominate electron impact dissociation mechanisms involving the whole vibrational ladder for E/N<50Td, the two mechanisms being competitive for E/N>50Td.
