Nuclear Structures

The properties of light exotic nuclei far off β-stability are studied using relativistic mean field (RMF) models considering the nonlinear isoscalar-isovector coupling terms that modify the density dependence of the symmetry energy. The ρNN tensor coupling is included. The neutron thickness of some light exotic nuclei near neutron drip lines is as uncertain as that of heavy nuclei. The uncertainty of these light exotic nuclei is enhanced by the inclusion of the ρNN tensor coupling subject to the 2s1/2 occupation of the out-layer neutrons. The charge density distribution of exotic nuclei on both sides of drip lines are considerably modified by the isospin dependent interactions. The role of multi-Λ hypernuclei in extending the drip lines are discussed.

Qualitative Analyses

The halo structures in some light nuclei are investigated systemically with the nuclear asymptotic normalization coefficient (ANC) method and the relativistic mean-field (RMF) theory. Some important results about the halo structures in mirror nuclei are obtained, and some qualitative analyses are made to explore the role of Coulomb effects on the formation of proton halo nuclei.

Relativistic Mean Field

For the nuclear many body problem at high densities, formulated in the framework of a relativistic mean-field theory, we investigate in detail the compression modulus of nuclear matter as a function of the effective nucleon mass. We include consistently in our modelling chemical equilibrium as well as baryon number and electric charge conservation and investigate properties of neutron stars. Among other predictions we focus on the dependence of the maximum mass of a sequence of neutron stars as a function of the compression modulus and the nucleon effective mass.
