摘要：

We report on the experimental study of the angular distributions of photons for the time-reversed photoionization process, i.e., the radiative electron capture (REC), in relativistic atomic collisions involving high-Z projectiles. Whereas former investigations focused on initially bare projectiles, we here extend our studies to heavy few-electron ions (H-, He- and Li-like uranium) in order to elucidate the importance of electron - electron interaction for photoionization in the realm of high-Z ions.
