Electron-impact cross sections for the dissociation process of vibrationally excited He + 2 molec... more Electron-impact cross sections for the dissociation process of vibrationally excited He + 2 molecular ion, as a function of the incident electron energy are calculated for the dissociative transition X 2 Σ + u → A 2 Σ + g by using the R-matrix method in the adiabatic-nuclei approximation. The potential energy curves for the involved electronic states and target properties, also calculated with the R-matrix method, were found to be in good agreement with the results reported in literature.

Resonant vibrational excitation cross sections and the corresponding rate coefficients for electr... more Resonant vibrational excitation cross sections and the corresponding rate coefficients for electron-N 2 collisions occurring through the N − 2 (X 2 Π g ) resonant state are reviewed. New calculations are performed using accurate potential energies curves for the N 2 electronic ground state, taken from literature, and for the N − 2 resonant state, obtained from R-matrix calculations. The calculations are extended also to the resonant excitation processes involving the N 2 ground state vibrational continuum, leading to dissociation. Electron impact dissociation is found to be significant from higher vibrational levels. Accurate analytical fits for the complete set of the rate coefficients are provided. The behavior of the dissociative cross sections is investigated for rotationally excited N 2 molecules, with J = 50, 100 and 150 and for different vibrational levels.
