The techniques of relativistic many-body calculations on atoms and ions have been used to reformulate the multiconfigurational Dirac-Fock techniques in such a way that good wave functions can be obtained with the same accuracy as with many-body perturbation theory, and a relationship between both approaches has been established. As an example the hyperfine interactions of the 7{ital s}, 7{ital p}{sub 1/2}, and 7{ital p}{sub 3/2} states of Ra{sup +} have been successfully calculated and are in good agreement with experiment.
