本文在Born一阶近似下,建立了一种能够方便计算各种过程的高能原子(或离子)碰撞截面的理论计算方法。对各种碰撞过程,进行了详细的理论分析,并对已有实验结果的H+,e,H,H-四种入射粒子与Na(3s→3p)的碰撞激发过程进行了理论计算。与实验结果的比较是令人满意的。Based on the first Born approximation, we develope a simple theoretical method to calculate the cross sections of various high energy atomic collision processes. For the 4 kinds of incident particles (H+, e-, H, H-) our theoretical cross sections for the target-atom excitation process Na(3s-3p) are consistent with the recent absolute experimental measurement.
