We report computational integral and differential cross sections for electron scattering by two different polar molecules, HCN and pyrimidine, over a broad energy range. We employ, for low energies, either the single-centre expansion (ePOLYSCAT) or the R-matrix method, while for the higher energies we select a corrected form of the independent-atom representation (IAM-SCAR). We provide complete sets of integral electron scattering cross sections from low energies up to 10,000 eV. Our present calculated data agree well with prior experimental results.
我们报告了在很宽的能量范围内，两种不同极性分子HCN和嘧啶与电子散射的计算积分截面和微分截面。对于低能情况，我们采用单中心展开法（ePOLYSCAT）或R矩阵方法，而对于高能情况，我们选择独立原子表示法的一种修正形式（IAM-SCAR）。我们提供了从低能到10000 eV的完整电子散射积分截面集。我们目前的计算数据与先前的实验结果吻合良好。
