摘要：

The 2(2)P1/2-2(2)S1/2 (lowest-excited-state to ground-state) energy splitting in lithiumlike uranium, which has large quantum-electrodynamic corrections, has been measured using Doppler-tuned spectrometry. Our result, 280.59 +/- 0.10 eV, is more precise than current theory and is an 80-fold improvement over the previous most precise measurement of the Lamb shift in (heliumlike) uranium.
