本文对630 keV/u的H ~+ +He碰撞中的转移电离进行了运动学上完整的理论计算和实验研究。实验和理论进行了比较，在动量空间中的全微分截面的最详细的水平。这使我们能够明确地确定从抖脱和二进制遇到机制的反应的贡献。结果表明，电子转移和电离的同时是高度敏感的试验初始状态波函数的质量。
We present kinematically complete theoretical calculations and experiments for transfer ionization in H + +He collisions at 630 keV/u. Experiment and theory are compared on the most detailed level of fully differential cross sections in the momentum space. This allows us to unambiguously identify contributions from the shake-off and binary encounter mechanisms of the reaction. It is shown that the simultaneous electron transfer and ionization is highly sensitive to the quality of a trial initial-state wave function.
