Electron impact ionization cross section of metastable N2(A Σu+)

Journal ArticleExtensive studies of electron impact cross sections have been carried out both experimentally and theoretically for a number of ground state atoms and molecules.1 In general, as the electron energy is increased, such cross sections rise from a threshold at the ionization potential to a peak at an electron energy roughly 4-6 times the threshold energy, before falling monotonically
