摘要：

The lifetime of the 2 P-3(0) state in He-like uranium has been measured in a beam-foil time-of-flight experiment at the Gesellschaft fur Schwerionenforschung accelerator facility with the result tau(2 P-3(0)) = 58.2(9.5) ps. With the measured lifetime it is possible to derive a value of Delta E-2s(Lamb) = 76.3 +/- 20.6 eV for the n = 2 Lamb shift in uranium. (c) 2005 Elsevier B.V. All rights reserved.
