We present the uncertainty discussion of a recent experiment performed at the GSI storage ring ESR for the accurate energy measurement of the He-like uranium 1s2p<sup>3</sup>P<sub>2</sub>→ 1s2s<sup>3</sup>S<sub>1</sub> intra-shell transition. For this propose we used a Johann-type Bragg spectrometer that enables to obtain a relative energy measurement between the He-like uranium transition, about 4.51 keV, and a calibration x-ray source. As reference, we used the K<sub>α</sub> fluorescence lines of zinc and the Li-like uranium 1s<sup>2</sup>2p<sup>2</sup>P<sub>3/2</sub> → 1 s<sup>2</sup>2s <sup>2</sup>S<sub>1/2</sub> intra-shell transition from fast ions stored in the ESR. A comparison of the two different references, i.e., stationary and moving x-ray source, and a discussion of the experimental uncertainties is presented. |
