r -矩阵方法被用于研究h2_2和co2体系的电子（再）散射。这是用英国分子r矩阵包计算完成的。再散射与电子分子在接近中性分子的几何形状上对相关阳离子的再散射的相似性构成了我们初始模型的基础。初步计算了氢分子和二氧化碳分子的截面和特征相和。它们在所研究的能量范围内表现出高度共振行为，这在通道阈值接近时尤为明显。初步结果表明，共振现象的包含对电子再散射实验的解释至关重要。本文还介绍了与线极化实验相关的对称弹性微分截面，并讨论了建立更现实模型的前景。
The R-matrix method is being used to investigate electron (re-)scattering for the H2and CO2systems. This is being done computationally using the UK molecular R-matrix package. The similarity of re-scattering to electron–molecule scattering off the associated cations at geometries near to those of the neutral molecules forms the basis of our initial model. Preliminary cross-sections and eigenphase sums have been calculated for molecular hydrogen and carbon dioxide. These show highly resonant behaviour in the energy range studied and this is particularly pronounced as channel thresholds are approached. The initial results suggest that inclusion of resonance phenomena could be vital for interpretation of electron re-scattering experiments. Elastic differential cross-sections for symmetries relevant to experiments performed using linear polarization are also presented and prospects for a more realistic model are discussed.
