Tests of quantum electrodynamics in few-electron very high-Z ions

  • 1. Lawrence Berkeley Lab., CA (USA). Materials and Molecular Research Div.

Description

This article discusses our measurement of the Lamb shift in heliumlike uranium and outlines future tests of QED using few-electron very high atomic number (Z) ions. Our recently reported Lamb shift value of 70.4 (8.3)eV for the one-electron Lamb shift in uranium is in agreement with the theoretical value of 75.3 (0.4)eV. The experimental value was extracted from a beam-foil time-of-flight measurement of the 54.4 (3.4)ps lifetime of the 1s2p1/23P0 state of helium-like uranium. (orig.)
