The hyperfine structure of short-lived trapped super(211,209Ra) super(+) ions was investigated by means of laser spectroscopy. The hyperfine structure constants A and B of the [inline image][inline image] 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 super(211Ra) super(+). These measurements provide a test for the atomic theory required for upcoming experiments on atomic parity violation and atomic clocks.
