Relativistic density-dependent Hartree-Fock approach for finite nuclei.
The self-energy of the Dirac Brueckner-Hartree-Fock calculation in nuclear matter is parametrized by introducing density-dependent coupling constants of isoscalar mesons in the relativistic Hartree-Fock (RHF) approach where isoscalar meson σ , ω and isovector meson π , ρ contributions are included. The RHF calculations with density dependent coupling constants obtained in this way not only repr...
متن کاملS ep 1 99 7 Relativistic Brueckner - Hartree - Fock calculations with explicit intermediate negative energy states
In a relativistic Brueckner-Hartree-Fock calculation we include explicit negative-energy states in the two-body propagator. This is achieved by using the Gross spectator-equation, modified by medium effects. Qualitatively our results compare well with other RBHF calculations. In some details significant differences occur, e.g, our equation of state is stiffer and the momentum dependence of the ...
متن کاملNN correlations and relativistic Hartree-Fock in finite nuclei.
Two different approximation schemes for the self-consistent solution of the relativistic Brueckner-Hartree-Fock equation for finite nuclei are discussed using realistic One-Boson-Exchange potentials. In a first scheme, the effects of correlations are deduced from a study of nuclear matter and parameterized in terms of an effective σ, ω and π exchange. Employing this effective interaction rela-t...
متن کاملFinite jellium models. I. Restricted Hartree-Fock calculations.
Restricted Hartree-Fock calculations have been performed on the Fermi configurations of n electrons confined within a cube. The self-consistent-field orbitals have been expanded in a basis of N particle-in-a-box wave functions. The difficult one- and two-electron integrals have been reduced to a small set of canonical integrals that are calculated accurately using quadrature. The total energy a...
متن کاملStrange nuclear matter within Brueckner-Hartree-Fock theory
We have developed a formalism for microscopic Brueckner-type calculations of dense nuclear matter that includes all types of baryon–baryon interactions and allows to treat any asymmetry on the fractions of the different species (n, p,Λ,Σ−,Σ0,Σ+,Ξ− and Ξ0). We present results for the different single–particle potentials focussing on situations that can be relevant in future microscopic studies o...
