Anisotropy in Ion Collisions and Ion Spectroscopy (Physics)

原子物理学的若干研究方向将继续进行。这包括：(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阱中，或者将以来自ECR离子源的低能量束的形式进行研究。同步辐射将用于存储离子的顺序光电离。(2)离子的各向异性激发，包括离子表面擦碰碰撞产生取向态的研究，导致圆极化辐射的发射，以及低能约束离子捕获自旋极化氢原子的电子。(3)光谱学研究包括存储的、亚稳的类氦Be离子的激光光谱学，以及来自ECR源的高电荷离子的某些基态精细结构跃迁的激光光谱学。同步加速器x射线将用于产生一种冷的、储存的多电荷离子气体，这种气体具有有趣的特性，并可作为离子光电离研究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.
