Phys. Rev. Lett. 100, 160404 (2008) [4 pages]Fundamental Constants and Tests of Theory in Rydberg States of Hydrogenlike IonsReceived 30 November 2007; published 22 April 2008 A comparison of precision frequency measurements to quantum electrodynamics (QED) predictions for Rydberg states of hydrogenlike ions can yield information on values of fundamental constants and test theory. With the results of a calculation of a key QED contribution reported here, the uncertainty in the theory of the energy levels is reduced to a level where such a comparison can yield an improved value of the Rydberg constant. © 2008 The American Physical Society URL:
