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.

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。 这种情况为对这种状态的结构进行极其精确的计算提供了机会，结合了相对论和辐射校正，而没有非相对论结构的不确定性。 它成为基础原子理论的试验场，特别是专门针对少数电子系统的原子理论。 里德堡态是通过中和加速离子束产生的。 使用 CO2 激光和斯塔克电离检测高 L 里德伯态。 高精度光谱学是使用微波方法来观察相同 n 的状态之间的转变。
