However, for the collision processes in He target, a large discrepacy between the CTMC results and experimental measurement is found. As is well known, the microcanonical distributions of bounded electrons in CTMC method is quite different from quantal distributions, we modified the initial microcanonical distribution by using eleven different ionization thresholds of electron bounded in target. With modification, we calculated the collisional process of O~(3+) with He, and the total cross sections of all processess are calculated as a function of the incident energies. The agreement with experiments is improved by the modified distributions.

但由于靶电子的微正则分布与量子分布有很大不同，在计算离子与He靶碰撞时发现结果与实验差距很大，我们基于使用多个系统总能量U值，对初始电子的微正则分布进行了优化，使其更接近于量子力学的径向空间分布，然后计算了O~(3+)与氦原子随入射离子能量变化的各种反应过程截面，发现优化极大地提高了计算精度，特别是我们的模型对于描述单电子、双电子丢失过程非常成功。
