This work involves a two-pronged approach to fundamental studies in atomic physics. In the first, the technique of recurrence spectroscopy will be combined with that of resonance fields to obtain new information about the crossover between quantum and classical physics. Particular attention will be paid to that portion of the motion that approaches chaos. The second effort is the precision determination of the Rydberg constant through measurement of transition frequencies among high Rydberg levels in the atom. By making measurements between Rydberg levels, QED and nuclear contributions to the energies are negligible, and the result represents an independent determination of this fundamental constant which can serve as a control for the more traditional approaches.

这项工作涉及一种两管齐下的原子物理学基础研究方法。 首先，将复发光谱技术与共振场相结合，以获取有关量子和经典物理之间交叉的新信息。 特别关注临近混乱的动议的部分。 第二个工作是通过测量原子高rydberg水平之间的过渡频率来确定Rydberg常数。 通过在Rydberg级别之间进行测量，QED和对能量的核贡献可以忽略不计，结果代表了对这个基本常数的独立确定，这可以作为更传统的方法的控制。
