The hyperfine structure of short-lived trapped 211,209Ra + ions was investigated by means of laser spectroscopy. The hyperfine structure constants A and B of the 6d 2D3/2 level were determined. There is a 2.2 standard deviation difference between the theoretical and the more accurate experimental value for the B coefficient of 211Ra+. These measurements provide a test for the atomic theory required for upcoming experiments on atomic parity violation and atomic clocks.
