The K-shell photoelectric effect for a hydrogenlike U91+ ion is studied by its time-reversed process occurring in relativistic collisions between bare uranium ions and low- Z target atoms. In the time-reversed situation, an electron is captured into the 1s ground state with the simultaneous emission of a photon. We present an angular differential study of these transitions for laboratory observation angles between nearly 0° and 150°. Our observation of photon emission close to 0° allowed us to identify spin-flip contributions to the photoionization process and to determine their relative strength.
