Abstract
We present a new experiment for the accurate study of the intrashell transition 1s2p 3P2 → 1s2s 3S1 in helium-like uranium near 4.5 keV using a Johann-type Bragg spectrometer with a spherically bent crystal. The focusing property of the bent crystal enhances the spectrometer's efficiency compared to flat crystal spectrometers and it will enable us, for the first time, to evaluate, accurately, the Lamb shift for n = 2 states in highly charged helium-like ions. The data will be acquired at the storage ring ESR of GSI using a fast H-like uranium beam colliding with a gas target. This measurement will provide the most sensitive test for the relativistic electron–electron interaction in a strong Coulomb field.PACS Nos.: 07.85.Nc, 12.20.Fv, 29.30.Kv and 32.30.Rj
