Abstract
The differential cross-sections (DCS) of the low-energy electron–N 2 scattering are studied using the vibrational close-coupling (VCC) method and vibrational scattering potentials which include static, exchange and polarization contributions. The polarization is obtained based on the ‘better than adiabatic dipole’ (BTAD) and the ‘distributed spherical Gaussian’ (DSG) respectively. The converged (0 → 0, 0 → 1, 0 → 2, 0 → 3) DCS are obtained with the impact energies being the resonance's first two elastic scattering peaks – approximately 1.90 eV and 2.10 eV. Calculations from both polarization potentials agree with experimental results.
