In this study, the degree of linear polarization of the K-REC radiation was measured and compared with rigorous relativistic calculations as well as with the previous results recorded for U$^{92+}$. Owing to the improved detector technology a significant gain in precision of the present polarization measurement is achieved compared to the previously published results. The obtained data confirms that for medium-Z ions such as Xe the REC process is a source of highly ","authors_text":"A. Gumberidze, A. Surzhykov, C. Brandau, C. Kozhuharov, C. Trageser, D.F.A.
