An adiabatic approximation in which the eikonal elastic amplitude for fixed molecular orientation is used as input is employed for the calculation of pure elastic scattering (J = 0..-->..J' = 0 and J = 1..-->..J' = 1), pure rotational excitation (J = 0..-->..J' = 2 and J = 1..-->..J' = 3), and orientationally averaged elastic cross sections of the nitrogen molecule in its ground electronic and vibrational states using electrons as incident particles. Both differential and integral cross sections are computed at electron energies 20--200 eV. Total momentum-transfer cross sections are also calculated. The effect of target polarization is considered in the effective electron-molecule potential. The effect of electron exchange is not taken into account. Results obtained are compared with those of other theoretical and experimental workers. The qualitative features of the rotational-excitation cross sections are found to resemble those of the hydrogen molecule. Small-angle experimental elastic cross sections are well reproduced.
