Anisotropy in Ion Collisions and Ion Spectroscopy (Physics)

原子物理学的几个研究方向将继续下去。这些包括：(1)低能、多电荷离子的碰撞和光谱研究。这些离子将被限制在离子陷阱中，或者将以来自ECR离子源的低能束的形式进行研究。同步辐射将用于存储离子的顺序光电离化。(2)离子的各向异性激发，包括研究离子-表面擦伤碰撞产生取向态，导致发射圆极化辐射，以及低能受限离子从自旋极化的氢原子中俘获电子。(3)光谱研究，包括激光光谱存储，亚稳态类氦铍离子，以及ECR源产生的高电荷态离子的某些基态精细结构跃迁的激光光谱。同步加速器x射线将被用来产生一种冷的、储存的多电荷离子气体，它具有有趣的性质，并作为研究离子的光致电离以及其他研究的目标。

Several lines of research in atomic physics will be continued. These include: (1) Collision and spectroscopy studies on low energy, multi-charged ions. These ions will be confined in ion traps, or will be studied in the form of low energy beams from an ECR ion source. Synchrotron radiation will be used for sequential photoionization of stored ions. (2) Anisotropic excitation of ions, including the study of the production of oriented states by ion-surface grazing collisions, resulting in the emission of circularly polarized radiation, and the capture by low energy confined ions of electrons from spin-polarized hydrogen atoms. (3) Spectroscopic studied including laser spectroscopy stored, metastable helium-like Be ions, and laser spectroscopy of certain ground state fine-structure transitions of highly- charged ions from the ECR source. Synchrotron x-rays will be used to produce a cold, stored multi-charged ion gas, which has interesting properties, and serves as a target for the study of photoionization of ions as well as other research.
