利用扭曲波Born交换近似方法计算了Ne+,…,Ne6+的电子碰撞电离截面,计算结果同实验和其他理论结果相一致.为满足实际应用需要,给出了高精度的拟合公式.还讨论了扭曲波Born交换近似方法对低电离度离子的适用性以及交换势的引进对计算结果的影响.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.
