我们测量了16 MeV O(7+)+He碰撞中单电离和转移电离(TI)的全微分截面。影响单次电离的主要碰撞参数大约比Ti大一个数量级。因此，与前者相比，后者的射束相干程度要高得多。测量数据表明，作为结果，TI受到单次电离中不存在的干扰效应的显著影响。
We have measured fully differential cross sections for single ionization and transfer ionization (TI) in 16 MeV O(7+)+He collisions. The impact parameters mostly contributing to single ionization are about an order of magnitude larger than for TI. Therefore, the projectile beam was much more coherent for the latter compared to the former process. The measured data suggest that, as a result, TI is significantly affected by interference effects which are not present in single ionization.
