Relativistic mean-field study to odd-A nuclei far from stability

Ground state properties of recently discovered Ddd-A nuclei near the partic le-drip-line have been investigated in the relativistic mean-field model. S pecial emphasis is placed on the effect of the spatial component of vector meson fields on ground state properties which is due to breaking of time re versal invariance for odd-A nuclei. Calculations show that its contribution to binding energies, radii and single particle energies is small but canno t be neglected completely for some drip-line nuclei because the last nucleo n in them is very weakly bound. Calculated binding energies are in reasonab ly good agreement with present experimental data and estimated values in ma ss tables. The structure of newly discovered nuclei is also discussed.
