我们描述了一个微扰的方法来解决耦合的外部区域方程的电子碰撞激发的中性原子，我们已经实现了计算机代码STGF。我们比较了中性Be和H的STGF结果与我们用非微扰R-矩阵传播子代码FARM获得的结果。一般在这里获得的优秀的协议指向未来扩展的相关代码的计算的能量水平和辐射率在负离子，光剥离截面和自由-自由电子跃迁数据中存在的中性原子。
We describe a perturbative approach to the solution of the coupled outer-region equations for the electron-impact excitation of neutral atoms, and which we have implemented within the computer code STGF. We compare the results from STGF for neutral Be and H with those that we have obtained with the non-perturbative R-matrix propagator code FARM. The excellent agreement obtained in general here points the way to the future extension of related codes for the calculation of energy levels and radiative rates in negative ions, photo-detachment cross sections and free-free electron transition data in the presence of a neutral atom.
