Observation of the 2p3/2 -> 2s1/2 intra-shell transition in He-like uranium
Résumé
We present the first identification and energy measurement of the 1s2p 3P2 → 1s2s 3S1 transition in He-like uranium. The experiment was performed at the internal gas-jet target of the ESR storage ring at GSI by means of a Bragg crystal spectrometer. Using the 1s2 2p 2P3/2 → 1s2 2s 2S1/2 transition in Li-like uranium as reference, we obtained an accuracy in the order of 0.01%, which provides, at present, the most accurate test of many-body and QED contributions in very heavy He-like ions
