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.

这个实验和计算研究计划继续使用递归光谱技术在电场中研究里德伯原子和分子。 量子力学的原子波函数并不能提供一种方法来容易地可视化原子的动力学，而递归光谱学结合半经典理论，提供了一个物理上理解里德堡电子通过其经典轨道的运动。 回归光谱将用于研究经典电离阈值以上的回归以及由较高激发初态和较高角动量态的回归引起的回归。 这些研究将在氦、复杂原子和简单分子上进行。 实验学家和理论家之间的强烈互动是该计划的一个标志。
