Multi-electron process in slow highly charged ion-atom and ion-molecule collisions will be investigated by means of time-of-flight coincidence measurements of Auger electrons, scattered projectiles and target recoil ions or fragments. In addition to the Auger electron energies, final projectile and recoil ion or fragment charge states, the measurements will simultaneously provide the Q-values or the kinetic energy release distributions and angular distribution information by means of recoil ion momentum spectroscopy. The experiments will be carried out at the multi-charged ion research facility at the University of Nevada, Reno.

利用俄歇电子、散射射弹和靶反冲离子或碎片的飞行时间符合测量，研究了高电荷态离子与原子和离子与分子慢碰撞中的多电子过程。 除了俄歇电子能量、最终射弹和反冲离子或碎片电荷状态之外，测量还将通过反冲离子动量谱同时提供Q值或动能释放分布和角分布信息。 实验将在位于里诺的内华达州大学的多电荷离子研究设施进行。
