采用能级-能级扭曲波方法中的柔性原子程序（FAC）计算了W q+（q= 4-5）的电子碰撞单电离截面，并考虑了显式分支比.计算的截面与现有的理论和实验结果进行了详细的比较。在考虑通道贡献的情况下，计算的电离截面与实验测量的电离截面一致。但是，当考虑所有通道的贡献时，目前的计算结果比实验测量值要大。一些重要的通道激发自电离（EA）的贡献，如激发到更高的更高
Electron-impact single ionization cross sections for W q+(q= 4–5) were calculated using the flexible atomic code (FAC) in the level-to-level distorted-wave method, considering the explicit branching ratio. The calculated cross sections are compared with the available theoretical and experiment results in detail. In the case of the contribution from the same channles as the available theoretical results, all of the calculated ionization cross sections agree with the experimental measured cross sections. But the present calculated results are larger than the experimental measurement when all channels contributions are included. Some important channels excitation autoionization (EA) contributions, such as the excitation to higher higher
