We discuss two different approximation schemes for the self-consistentsolution of the {\it relativistic} Brueckner-Hartree-Fock equation for finitenuclei. In the first scheme, the Dirac effects are deduced from correspondingnuclear matter calculations, whereas in the second approach the local-densityapproximation is used to account for the effects of correlations. The resultsobtained by the two methods are very similar. Employing a realisticone-boson-exchange potential (Bonn~A), the predictions for energies and radiiof $^{16}$O and $^{40}$Ca come out in substantially better agreement withexperiment as compared to non-relativistic approaches. As a by-product of ourstudy, it turns out that the Fock exchange-terms, ignored in a previousinvestigation, are not negligible.Comment:
