摘要 利用相对论修正扭曲波玻恩交换近似 ,计算了 8个类钠离子的电子碰撞直接电离和激发自电离截面 .基于这些结果 ,给出了计算类钠等电子系离子 (18≤Z≤ 39)直接电离和激发自电离截面的高精度拟合公式 .计算结果与现有的实验值和其他理论值比较 。 By using a distorted-wave Born exchange ( DWBE ) approximation method including the relativistic correction, we calculated the direct ionization and excitation autoionization cross sections of eight Na-like ions. Based on the calculated results, we present two empirical formulas with high accuracy for calculating direct ionization and excitation autoionization cross sections. Our results are in good agreement with the experiment data and other theoretical values.
