Abstract

Quantum calculations of the resonant vibrational excitation of N₂ by electron impact are carried out using a model potential for exchange and correlation-polarization forces and exact static interaction. The inelastic process is treated within a coupled channel, space-frame formulation and final cross-sections are tested for convergence within less than of their values. Comparison with the experiments yields very good agreement with the latter data in the resonance region and suggests possible extension to calculations near the threshold openings for rovibrational inelastic processes induced by electron impact.
