摘要：

The energy differential cross sections for electron-impact ionization of H-and He-like ions have been calculated using a distorted-wave Born exchange approximation. The calculated results are well fitted to a two-parameter Gaussian function. These results from the fitting, which reproduce the calculated cross sections with an average error of about 4%, are in good agreement with experimental results.
