Microwave/Optical Spectroscopy of Helium and H2 Rydberg States

该提案要求研究“氦和H2里德伯态的微波/光学光谱”。重点是在允许电子几乎完全空间分离的条件下，研究这两个电子系统中的高里德伯态。这种情况为对这些状态的结构进行极其精确的计算提供了机会，在非相对论性结构中结合相对论性和辐射性修正，而不存在不确定性。它成为基本原子理论的试验场，特别是专门研究少数电子系统的试验场。里德伯态是通过中和加速离子束而产生的。利用CO2激光和斯塔克电离检测高l里德堡态。高精度光谱学采用微波方法来观察相同n的状态之间的跃迁。

This proposal calls for the study of, "Microwave/Optical Spectroscopy of Helium and H2 Rydberg States". The focus is the study of high Rydberg states in these two electron systems under conditions which allow virtually complete spatial separation of the electrons. The circumstances provides an opportunity for extremely precise calculations of the structure of such states, incorporating relativistic and radiative corrections without uncertainty in the non- relativistic structure. It becomes a testing ground for fundamental atomic theory, especially as specialized to few electron systems. The Rydberg states are produced by neutralizing an accelerated ion beam. The high-L Rydberg states are detected using a CO2 laser and Stark ionization. High precision spectroscopy is carried out using microwave methods to look at transitions between states of the same n.
