The hyperfine structure of all levels of the metastable 3/ital d//sup 2/ configuration in Sc ii has been measured with high precision by collinear fast-ion laser-rf double-resonance spectroscopy. The double-resonance technique improved the precision of the earlier results by more than a factor of 150. The enhanced precision made possible for the first time a meaningful comparison between experimental and multiconfiguration Dirac-Fock calculated /ital B/ values. The comparison showed that, unlike the /ital A/ values where disagreements between experiment and theory could be greater than 400%, the /ital B/ values were well predicted.
