结果表明，奥尔森和萨洛普描述的离子原子碰撞经典轨迹蒙特卡罗处理过程并没有提供定义轨迹初始条件的所有参数的均匀统计分布。重新计算了 ${\mathrm{H}}^{+}$ 与 H 在 25 至 600 keV 之间的 H 能量下碰撞的碰撞电离和电荷转移截面，消除了这一缺陷，并与使用 Olson 和 Salop 的程序获得的结果以及实验结果进行了比较。
It is shown that the procedure described by Olson and Salop for classical-trajectory Monte Carlo treatment of ion-atom collisions does not provide a uniform statistical distribution of all the parameters defining the initial conditions of a trajectory. Impact-ionization and charge-transfer cross sections for collisions of ${\mathrm{H}}^{+}$ with H at H energies between 25 and 600 keV are recalculated eliminating this failing and compared with those obtained using the procedure of Olson and Salop and with experimental results.
