我们提出了一种新的实验工具，允许对激光冷却原子的分裂过程进行运动学完整的研究。这种名为“MOTReMi”的仪器是磁光阱（MOT）和反应显微镜（ReMi）的结合。在离子存储环中操作，新的设置使我们能够以前所未有的精度和细节研究离子-原子快速碰撞的动力学。在与1:5 MeV/amu O8+-Li碰撞的首次实验中，研究了价电子的纯电离和锂靶的电离激发。
We present a novel experimental tool allowing for kinematically complete studies of break-up processes of laser-cooled atoms. This apparatus, the 'MOTReMi,' is a combination of a magneto-optical trap (MOT) and a reaction microscope (ReMi). Operated in an ion-storage ring, the new setup enables us to study the dynamics in swift ion-atom collisions on an unprecedented level of precision and detail. In the inaugural experiment on collisions with 1: 5 MeV/amu O8+-Li the pure ionization of the valence electron as well as the ionization-excitation of the lithium target was investigated.
