Radiative electron capture as a tunable source of highly linearly polarized x-rays

M. Vockert, G. Weber, H. Bräuning +27

The radiative electron capture (REC) into the K shell of bare Xe ions colliding with a hydrogen gas target has been investigated. In this study, the degree of linear polarization o…

Wavelength-dispersive spectroscopy in the hard x-ray regime of a heavy highly-charged ion: The 1s Lamb shift in hydrogen-like gold

T. Gassner, M. Trassinelli, R. Heß +40

Accurate spectroscopy of highly charged high-Z ions in a storage ring is demonstrated to be feasible by the use of specially adapted crystal optics. The method has been applied for…

Comparative study of the electron- and positron-atom bremsstrahlung

V. A. Yerokhin, A. Surzhykov, R. Märtin +2

Fully relativistic treatment of the electron-atom and positron-atom bremsstrahlung is reported. The calculation is based on the partial-wave expansion of the Dirac scattering state…

Observation of the 2p3/2 -> 2s1/2 intra-shell transition in He-like uranium

Martino Trassinelli, Ajay Kumar, Heinrich Beyer +17

We present the first observation of the 1s2p 3P2 ? 1s2s 3S1 transition in He-like uranium. The experiment was performed at the internal gas-jet target of the ESR storage ring at GS…
