Abstract
Reported triple differential cross sections (TDCS) for electron-impact ionization of nitrogen molecule have been calculated by employing distorted-wave Born approximation (DWBA) and independent-atom model (IAM), for incident electron energy of 500 eV, and ejected electron energies of 37 eV, 74 eV, and 205 eV, in coplanar asymmetric geometry. Scattering amplitudes of independent nitrogen atoms calculated in the DWBA were used to determine the TDCS of the molecule in IAM. The obtained results are compared to available experimental and theoretical data. Reasonably good qualitative and quantitative agreement was found for low to intermediate ejected electron energies, in terms of binary and recoil peak prediction. Quantitative discrepancies at higher ejected electron energies are attributed to the DWBA limitations.
