This experimental and computational research program continues the investigation of Rydberg atoms and molecules in electric fields using the technique of recurrence spectroscopy. Quantum mechanical atomic wavefunctions do not provide the means to easily visualize the dynamics of an atom, whereas recurrence spectroscopy, combined with semiclassical theory, provides a physical understanding of the motion of the Rydberg electron through its classical orbits. Recurrence spectroscopy will be used to investigate recurrences above the classical ionization threshold as well as recurrences resulting from higher excited initial states and recurrences of higher angular momentum states. These studies will be undertaken on helium, complex atoms, and simple molecules. A strong interaction between experimentalists and theorists is a hallmark of the program.

该实验和计算研究计划利用递归光谱技术继续研究电场中的里德伯原子和分子。 量子力学原子波函数无法提供轻松可视化原子动力学的方法，而递归光谱与半经典理论相结合，提供了对里德堡电子通过其经典轨道运动的物理理解。 递归光谱将用于研究高于经典电离阈值的重现以及由更高激发初始态和更高角动量状态的重现引起的重现。 这些研究将针对氦、复杂原子和简单分子进行。 实验学家和理论家之间的强烈互动是该项目的一个标志。
