Lifetime measurement of the metastable 2Â 3P0 state in He-like uranium

The lifetime of the 2 3P0 state in He-like uranium has been measured in a beam-foil time-of-flight experiment at the Gesellschaft für Schwerionenforschung accelerator facility with the result τ(2 3P0) = 58.2(9.5) ps. With the measured lifetime it is possible to derive a value of ΔE2sLamb=76.3±20.6eV for the n = 2 Lamb shift in uranium.
