摘要:

类氢离子的环形里德伯态理论的性质允许对能级进行高度精确的预测。特别是,由困扰低角动量态的有问题的核尺寸修正引起的不确定性对于高角动量态是可以忽略不计的。最大的不确定性的剩余来源可以解决的帮助下,量子电动力学(QED)的计算,包括一个新的非微扰的结果在这里报告。更严格的测试理论和改进的测定里德伯常量可能如果预测可以与精确的频率测量在这一制度。通过利用离子和Ryberg态的各种组合来确定基本常数和测试理论,可以增加信息的多样性。

英文摘要:

The nature of the theory of circular Rydberg states of hydrogenlike ions allows highly-accurate predictions to be made for energy levels. In particular, uncertainties arising from the problematic nuclear size correction which beset low angular-momentum states are negligibly small for the high angular-momentum states. The largest remaining source of uncertainty can be addressed with the help of quantum electrodynamics (QED) calculations, including a new nonperturbative result reported here. More stringent tests of theory and an improved determination of the Rydberg constant may be possible if predictions can be compared with precision frequency measurements in this regime. The diversity of information can be increased by utilizing a variety of combinations of ions and Ryberg states to determine fundamental constants and test theory.
