Abstract
The Schwinger multichannel formulation has been applied to study the role of electron correlation in low-energy e-N2 scattering. For the five nonresonant partial-wave channels studied here, 2Σg+, 2Σu+, 2Πu, 2Δg, and 2Δu, we find angular correlation to be much more important than radial correlation. Our results for the 2Σg+ channel are in agreement with those of Schneider and Collins [Phys. Rev. A 30, 95 (1984)]. Our calculated total and differential cross sections agree with experiment except for the differential cross sections at 1.5 eV. Our results are also compared with those obtained using model polarization potentials.
