使用 R 矩阵方法计算从阈值到 30 eV 的能量范围内 e-N2 散射的微分弹性和振动非弹性截面。在低能量下，横截面主要受众所周知的 2 Pi g 共振影响。在这个能量区域中，包括由于电子和核自由度耦合而产生的非绝热效应。在较高能量下，横截面以 2 Sigma u 共振为主。在这个能量区域，绝热近似是合适的。在可能的情况下将横截面与实验进行比较。总体而言，获得了良好的一致性，但一些差异表明了未来工作的方向。
The differential elastic and vibrationally inelastic cross sections for e-N2 scattering are calculated in the energy range from threshold to 30 eV using the R-matrix method. At low energies the cross sections are dominated by the well known 2 Pi g resonance. In this energy region non-adiabatic effects due to the coupling of the electronic and nuclear degrees of freedom are included. At higher energies the cross sections are dominated by the 2 Sigma u resonance. In this energy region the adiabatic approximation is appropriate. The cross sections are compared where possible with experiment. In general good agreement is obtained but some discrepancies suggest directions for future work.
