FINITE-NUCLEI CALCULATIONS BASED ON RELATIVISTIC MEAN-FIELD EFFECTIVE INTERACTIONS

The Dirac-Brueckner-Hartree-Fock calculations of nuclear matter are parametrized by the relativistic sigmaomega mean-field theory with scalar and vector nonlinear self-interactions. The effective interactions thus obtained are used in the relativistic mean-field studies of the structure of O-16 and Ca-40 nuclei without the introduction of additional free parameters. The calculated binding energies, single-particle spectra and charge radii agree quite well (although not satisfactorily) with experimental data and present an improvement over the nonrelativistic Brueckner-Hartree-Fock approximations.
