|Title:||Fundamental Constants and Tests of Theory in Rydberg States of Hydrogen-like Ions|
|Published:||April 22, 2008|
|Abstract:||A comparison of precision frequency measurements to quantum electrodynamics (QED) predictions for Rydberg states of hydrogen-like 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.|
