Many-Body Collision Dynamics Involving Particles and Antiparticles

该提案概述了一个项目，以研究基本的，但未解决的，多体问题的动力学。 原子碰撞是研究多体问题的特别合适的系统，因为可以精确地选择介于两体和具有非常大粒子数的物体之间的中间粒子数（3-10）。 将进行正电子、电子、质子和高电荷离子碰撞的单电离和多电离过程的高度微分和运动学完整的实验研究。 因此，在其他条件相同的情况下，直接比较粒子和反粒子之间的这种过程将成为可能。 多参数符合实验将结合最新技术，同时测量少体系统n个碰撞产物中的n-1个的动量矢量。

This proposal outlines a project to study the dynamics of the fundamental, but unsolved, many-body problem. Atomic collisions represent particularly suitable systems for studying the many-body problem because intermediate particle numbers (3-10) between two-body and bodies with very large particle numbers can be precisely selected. Highly differential and kinematically complete experimental studies on single and multiple ionization processes by positron, electron, proton, and highly charged ion impact will be performed. Thus, direct comparisons for such processes between particles and antiparticles under otherwise the same conditions will become possible. State-of-the-art technologies will be combined in multi-parameter coincidence experiments to simultaneously measure the momentum vectors of n-1 of the n collision products of the few-body systems.
