| 摘 要： | 使用扭曲波玻恩交换(DWBE)近似计算Al^q (q=0～12)的电子碰撞电离截面和速率系数，其中电离截面的高能行为由Bethe系数决定。分析了计算数据随电离度的变化规律，并且与可得到的实验的和其他计算的数据进行了比较，表明结果可靠。

| Abstract: | The DWBE method has been used to calculate the cross sections and of electron impact ionization of Alq+(q=1～12). We have related the scaled cross sections to the Bethe coefficients at high energy regime. The latter can be obtained by integral of cross section of photoionization. These cross sections are then fit to obtain corresponding rate coefficients. According to our calculations, the scaled cross sections vary slowly as the charge state change. Our results are in good agreement with those of experiment and other theoretical calculations. |
