X-rays following 116.15 MeV/u collisions of Li-like uranium with hydrogen target were measured at different observation angles with regard to the ion beam direction. From the measured experimental spectra combined with radiative electron capture calculations, we obtain angular distribution of characteristic x-rays following the resonance transfer and excitation. Our result shows a good qualitative agreement with theoretical predictions.
