A distorted-wave Born exchange (DWBE) approximation is used to calculate the cross sections of electron-impact ionization for Ne+,…Ne6+.The comparison shows good agreement between theoretical and experimental results.We give empirical formulas with high precision to meet the requirements of applications.The validity of the DWBE method in lowly ionized ions and the affect of the exchange potential on the calculated results are also discussed.
