Abstract
Recent advances in the development of 2D microstrip detectors open up new possibilities
for hard x-ray spectroscopy, in particular for polarization studies. These detectors make ideal
Compton polarimeters, which enable us to study precisely the polarization of hard x-rays. Here,
we present recent results from measurements of Radiative Electron Capture into the K-shell of
highly-charged uranium ions. The experiments were performed with a novel 2D Si(Li) Compton
polarimeter at the Experimental Storage Ring at GSI. Stored and cooled beams of U91+ and
U92+ ions, with kinetic energies of 43 MeV/u and 96 MeV/u respectively, were crossed with a
hydrogen gasjet. The preliminary data analysis shows x-rays from the K-REC process, emitted
perpendicularly to the ion beam, to be strongly linearly polarized.
