英文摘要	Ground state properties of carbon isotopes, including root-mean-square radii, neutron separation ener-gies, single particle spectra, and shapes are systematically studied with the deformed relativistic HartreeBogoliubov theory in continuum. The calculations with the effective interaction PK1 reproduce the available data reasonably well. The shell evolution in this isotopic chain is investigated by examining the single particle spectra. The inversion of neutron orbitals nu 2s(1/2) and nu 1d(5/2) compared with the order of neutron orbitals in stable nuclei is revealed in 15-20,22C when these nuclei are constrained to spherical shape. Neutron halos in C-15,C-19,C-22 are studied in detail and their halo structures are mainly caused by the inversion of (nu 2s(1/2), nu 1d(5/2)) and deformation effects. In particular, C-15 and C-22 are deformed halo nuclei with shape decoupling effects in ground states. (C) 2020 Elsevier B.V. All rights reserved.
