Abstract
The K-shell photoelectric effect for a hydrogenlike U91+ ion is studied by its time-reversed process occurring in relativistic collisions between ban uranium ions and low-Z target atoms. In the time-reversed situation, an ele ctron is captured into the Is ground state with the simultaneous emission o f a photon. We present an angular differential study of these transitions f or laboratory observation angles between nearly 0 degrees and 150 degrees. Our observation of photon emission close to 0 degrees allowed us to identif y spin-flip contributions to the photoionization process and to determine t heir relative strength. [S0031-9007(99)08948-6].
