Semiclassical Approach to Relativistic Nuclear Mean Field Theory

Incompressibility of nuclear matter, and Coulomb and volume-symmetry coefficients of nucleus incompressibility in the relativistic mean field theory.

Incompressibility of nuclear matter, and Coulomb and volume-symmetry coefficients of nucleus incompressibility in the relativistic mean field theory ABSTRACT The volume coefficient K(=incompressibility of the nuclear matter), the Coulomb coefficient K c , and the volume-symmetry coefficient K vs of the nucleus incom-pressibility are studied in the framework of the relativistic mean field theory...

Nuclear Mean Fields through Selfconsistent Semiclassical Calculations

Semiclassical expansions derived in the framework of the Extended ThomasFermi approach for the kinetic energy density τ(~r) and the spin-orbit density ~ J(~r) as functions of the local density ρ(~r) are used to determine the central nuclear potentials Vn(~r) and Vp(~r) of the neutron and proton distribution for effective interactions of the Skyrme type. We demonstrate that the convergence of th...

Relativistic Mean – Field Calculations of Λ and Σ Hypernuclei ∗ February 9 , 2008

Single–particle spectra of Λ and Σ hypernuclei are calculated within a relativistic mean–field theory. The hyperon couplings used are compatible with the Λ binding in saturated nuclear matter, neutron-star masses and experimental data on Λ levels in hypernuclei. Special attention is devoted to the spin-orbit potential for the hyperons and the influence of the ρ-meson field (isospin dependent in...
