其中采用了电子与离子系统的LS耦合表象，考虑了交换效应，仔细处理了碰撞矩阵元的角部分因子。

The LS coupling representation of electron -ion system is used, the exchange effect is taken into account and the angular factors of collision matrix elements are treated in detail.

一般可以避免这种情况的跟踪你的变换矩阵，将它应用到触摸是否碰撞。

You can in general avoid this by keeping track of your transformation matrix and applying it to the touch to see if it collides really.
