Measuring Higher-Level QED

Abstract:
A new experiment at Livermore National Lab has made the best measurement yet of a complicated correction to the simplest quantum description of how atoms behave. Livermore researchers did this by measuring the Lamb shift, a subtle shifting of quantum energy levels, including a first measurement of "two-loop" contributions, in a plasma of highly charged uranium ions.
