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 2[ital s][sub 1/2-]2[ital p][sub 3/2] transitions in eight ionization states bteween Li-like U[sup 89+] and Ne-like U[sup 82+] 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[plus minus]0.35 eV is found for the 2[ital s][sub 1/2] Lamb shift in Li-like U[sup 89+], in excellent agreement with theory.
