本文应用Schwinger多通道公式研究了电子关联在低能e-N2散射中的作用。对于本文研究的5个非共振分波通道，2 μ g+，2 μ u+，2 μ u，2Δg和2Δu，我们发现角相关比径向相关重要得多。我们对2 μ g+通道的结果与Schneider和柯林斯的结果一致[Phys.Rev.A30，95（1984）]。除了1.5eV处的微分截面外，我们计算的总截面和微分截面与实验结果一致。我们的结果也与使用模型极化势得到的结果进行了比较。
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.
