Abstract: (APS)
The density-dependent relativistic mean-field theory with σ, ω, and ρ mesons, as a parameter-free calculation, has been used to study the ground-state properties of Be12,14, Ne30,32, Ca60,62, and Zr122,124. A special emphasis is placed on the influence of the ρ tensor coupling on the neutron halo and on the spin-orbit splitting. It is shown for the first time that the inclusion of the ρ tensor coupling will lead to the isospin-dependent spin-orbit splitting although the binding energy and the radius of these nuclei are insensitive to it.- 21.10.Dr
