Fundamental constants and tests of theory in Rydberg states of hydrogenlike ions



Ulrich D. Jentschura, Peter Mohr, Joseph N. Tan, Benedikt J. Wundt


A comparison of precision frequency measurements to quantum electrodynamic (QED) theoretical predictions can be used to test theory and to obtain information regarding fundamental constants. We find that for Rydberg states, theoretical uncertainties due to the problematic nuclear size correction are very small. With the help of QED calculations, the largest remaining source of uncertainty can be eliminated. Theoretical predictions, taking advantage of the latest theoretical results, in combination with planned experiments, can lead to an improved value for the Rydberg constant.
