Abstract
The differential and total elastic cross sections for electron scattering by N2(1 Sigma g+) in the first Born approximation are calculated using various accurate multiconfiguration self-consistent-field (MCSCF) configuration-interaction wavefunctions. The most accurate wavefunction used in the present calculation includes correlation of the 2 sigma shells and gives a total energy of -109.321 02 Hartrees (Eh). Various electronic moments are also given for comparison with either experiments or other theoretical results. It is found that the effects of electron correlation on the total and differential cross sections at small scattering angles are not significant. However, the effect of electron correlation on the differential cross section is not negligible for momentum transfers around 5 approximately 6 AA-1.Keywords
