摘要：

The first Doppler-shift-free crystal-spectrometer measurement of stationary highly stripped uranium ions from a high-energy electron beam ion trap is presented. Thirteen 2s1/2-2p3/2 transitions in eight ionization states between Li-like U89+ and Ne-like U82+ are identified and measured with an accuracy as high as 37 ppm, providing benchmarks for testing relativistic correlation and quantum electrodynamic effects in highly charged multielectron ions. A value of 47.39 +/- 0.35 eV is found for the 2s1/2 Lamb shift in Li-like U89+, in excellent agreement with theory.
