中文摘要：
在现代物理的研究所基于反应显微镜，在分子的离子原子碰撞的反应机制试验性地被调查。这个系统的特征被为碰撞过程执行的一个运动学上地完全的实验说明。用记录技术和巧合测量的所谓的表模式数据，从分子的离子的每碎片的动量向量是由事件的记录事件。为 H2+ 分离反应的分子的轴的取向能在离线的分析为每个事件被决定。分子的离子的测量取向应碰撞的请求与那一样被相信在下面轴撤退近似。分子的取向的极的角度决定？
英文摘要：
Based on the reaction microscope at the institute of modern physics, the reaction mechanism in molecular ion-atom collisions is investigated experimentally. The features of this system is illustrated by a kinematically complete experhnent performed for the collision process. Using the so-called list-mode data recording technique and the coincidence measurement, the momentum vector of each fragment from the molecular ion were recorded event by event. The orientation of the molecular axis for H2^＋ dissociation reactions could be determined for each event in the off-line analysis. The measured orientation of the molecular ion is believed the same as the one at the instance of collision under axial recoil approximation. The polar angle resolution of the molecular orientation of ±8° was obtained.
