在20-5000能区研究了氢原子与反质子碰撞中的电离过程。eV直接解决一个半经典的时间依赖的薛？丁格方程与离散变量表示（DVR）算法的使用。在目前的半经典方法，只有一个自由度，即？和H之间的径向距离被经典地处理，并且所有其它自由度被量子力学地处理。因此，我们可以正确地考虑总角动量守恒，也自然地考虑+ H相对轨道的弯曲效应。
Ionization in collisions of atomic hydrogen with antiprotons () are studied in the energy region 20-5000?eV by solving directly a semiclassical time-dependent Schr?dinger equation with use of a discrete-variable-representation (DVR) algorithm. In the present semiclassical method, only one degree of freedom, i.e.?the radial distance between and H is treated classically and all the other degrees of freedom are treated quantum mechanically. Hence, we can consider correctly the conservation of the total angular momentum, and also naturally the bent effect of the relative trajectory of + H.
