计算再现众所周知的Ramsauer-Townsend效应的电子散射甲烷。用于电子与甲烷相互作用的理论模型包括（i）甲烷静态势，（ii）通过将入射波函数正交化到相同对称性的束缚波函数来近似的交换效应，以及（iii）选择极化势以在理论和实验总截面之间给出良好的一致性。
Calculations are described which reproduce the well known Ramsauer-Townsend effect in the scattering of electrons by methane. The theoretical model used for the interaction of an electron with methane includes (i) the methane static potential, (ii) exchange effects which are approximated by orthogonalizing the incident wavefunction to bound wavefunctions of the same symmetry and (iii) a polarization potential which is chosen to give good agreement between theoretical and experimental total cross sections.
