我们已经进行了低能弹性电子与一氧化二氮（N2 O）碰撞的理论研究，获得微分，积分和动量转移截面。极化效应被纳入电子-分子散射动力学。一个简单的，客观的，和物理动机的标准被引入构造一组紧凑的配置，准确地占在共振对称性的极化，同时避免过相关。我们的横截面与实验和早期的高级计算基本一致，大多数差异都很容易理解。然而，计算和测量的微分截面之间的某些差异仍然令人困惑。
We have carried out theoretical studies of low-energy elastic electron collisions with nitrous oxide (N2O), obtaining differential, integral, and momentum-transfer cross sections. Polarization effects are incorporated in the electron-molecule scattering dynamics. A simple, objective, and physically motivated criterion is introduced for constructing a compact set of configurations that accurately accounts for polarization in resonant symmetries while avoiding overcorrelation. Our cross sections are in generally good agreement with experiment and with earlier high-level calculations, and most differences are readily understood. However, certain discrepancies between the calculated and measured differential cross sections remain puzzling.
