ResumoCollision cross sections for rotational excitation processes of a molecular nitrogen by electron impact are calculated at the energy range of 0.01 to 3 eV. It is shown that integrated cross sections for rotationally inelastic scattering are noticeably enhanced by the short range interaction between the scattered electron and the target nitrogen molecule at the impact energy as low as 0.08 eV. At the energy region of the well-known \(\varPi_{g}\) resonance, it is confirmed that the cross section for the rotational excitation of j =0 to j '=4 becomes larger than that for j =0 to j '=2 by more than the ratio of statistical weight (2 j '+1) of the final rotational state j '. An explanation to this fact is given by analysing the expression of the integrated cross section.
