ResumoThe structure of carbon isotopes from the proton-drip-line nucleus 9C to the neutron-drip-line nucleus 22C has been systematically studied in the framework of the nonlinear relativistic mean-field theory with inclusion of deformations. Calculations show that the relativistic mean-field theory provides a reasonably good description of experimental binding energies and root-mean-square radii. The spin and parity of the ground state in 15,17,19C are correctly predicted to be (12)+, (32)+ and (12)+, respectively. The effect of deformations on the structure of exotic nuclei is discussed and a consistent explanation on the one-neutron halo in 19C is given.
