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继续使用复发光谱技术对电场中Rydberg原子和分子进行研究。 量子机械原子波函数不能提供轻松可视化原子动力学的手段，而复发光谱与半经典理论相结合，通过其经典轨道对Rydberg电子的运动提供了物理上的理解。 复发光谱法将用于研究高于经典电离阈值的复发，以及较高激发初始状态和较高角动量状态的复发产生的复发。 这些研究将以氦气，复杂原子和简单分子进行。 实验主义者和理论家之间的强烈互动是该计划的标志。
