The Λand Ξ-hyperon mean free paths in nuclei are firstly calculated in the relativistic mean field (RMF) theory. The real parts of the optical potential are derived from the RMF approach, while the imaginary parts are obtained from those of nucleons with the relations: U IY S = ασY · U IN S and U IY V = αωY ·U IN V . With the assumption, the depth of the imaginary potential for Ξ − is WΞ ≃ − 3....

Superdeformations in Relativistic and Non-Relativistic Mean Field Theories

The applications of the extensions of relativistic mean field (RMF) theory to the rotating frame, such as cranked relativistic mean field (CRMF) theory and cranked relativistic Hartree-Bogoliubov (CRHB) theory, for the description of superdeformed bands in the A ∼ 60, 140 − 150 and 190 mass regions are overviewed and compared briefly with the results obtained in non-relativistic mean field theo...

Relativistic mean-field dynamics of giant resonances

Models based on quantum hadrodynamics provide a consistent description of the nuclear many-body system in terms of interacting baryons and mesons. In the self-consistent mean-field approximation, the time-dependent model has been applied in the analysis of the dynamics of giant resonances. The calculated excitation energies and transition densities of isoscalar giant monopole resonances, restri...

Double-Λ hypernuclei in the relativistic mean-field theory

We study the properties of double-Λ hypernuclei in the relativistic mean-field theory, which has been successfully used for the description of stable and unstable nuclei. With the meson-hyperon couplings determined by the experimental binding energies of single-Λ hypernuclei, we present a self-consistent calculation of double-Λ hypernuclei in the relativistic mean-field theory, and discuss the ...
