Fundamental Experiments in Ion-Atom Collision Physics

涉及最基本的三体离子-原子碰撞系统的一系列实验正在进行中。将完成涉及氢原子靶的质子-光子符合实验，将基本三体离子原子碰撞系统的研究扩展到测量α粒子对原子氢的激发、弹性散射、电荷转移和电离的微分截面。这一系列实验将在涉及原子氢目标的阿尔法粒子-光子符合实验中达到高潮。符合实验获得的数据将提供关于散射幅度的大小和相对相位作为弹丸散射角和能量的函数的详细信息。拟议的实验使用了位于密苏里大学罗拉分校的独特设施的能力。他们将尽可能提供有关这些基本系统的最详细信息。

A series of experiments involving the most basic three-body ion-atom collision systems is underway. A proton-photon coincidence experiment involving an atomic hydrogen target will be completed to extend the study of basic three-body ion atom collision systems to the measurement of differential cross sections for excitation, elastic scattering, charge transfer, and ionization of an atomic hydrogen by alpha particles. This set of experiments will culminate in alpha particle-photon coincidence experiment involving an atomic hydrogen target. Data obtained from the coincidence experiments will provide detailed information on the magnitude and relative phase of the scattering amplitude as a function of the projectile scattering angle and energy. The proposed experiments use the capabilities of the unique facility located at the University of Missouri-Rolla. They will provide the most detailed information possible on these fundamental systems.
