Some Aspects of Nuclear Structure in Relativistic Approach

The nucleon effective interaction in the nuclear medium is investigated in the framework of the Dirac-Brueckner-Hartree-Fock (DBHF) approach.A new decomposition of the Dirac structure of nucleon self-energy in theDBHF is adopted for asymmetric nuclear matter.The properties of finite nuclei are investigated with the nucleoneffective interaction.The agreement with the experimental data is satisfactory.The relativistic microscopic opticalpotential in asymmetric nuclear matter is investigated in the DBHF approach.The proton scattering from nuclei iscalculated and compared with the experimental data.A proper treatment of the resonant continuum for exotic nuclei isstudied.The width effect of the resonant continuum on the pairing correlation is discussed.The quasiparticle relativisticrandom phase approximation based on the relativistic mean-field ground state in the response function formalism is alsoaddressed.
