| 英文摘要 | Halos and changes of nuclear magicities have been extensively investigated in exotic nuclei during past decades. The newly discovered Na-39 with the neutron number N = 28 provides a new platform to explore such novel phenomena near the neutron dripline of the sodium isotopic chain. We study the shell property and the possible halo structure in Na-39 within the deformed relativistic Hartree-Bogoliubov theory in continuum. It is found that the lowering of 2p orbitals in the spherical limit results in the collapse of the N = 28 shell closure in 39Na, and a well-deformed ground state is established. The pairing correlations and the mixing of pf components driven by deformation lead to the occupation of weakly bound or continuum p-wave neutron orbitals. An oblate halo is therefore formed around the prolate core in (39),Na-41, making Na-39 a single nucleus with the coexistence of several exotic structures, including the quenched N = 28 shell closure, Borromean structure, deformed halo, and shape decoupling. The microscopic mechanisms behind the shape decoupling phenomenon and the development of halos towards dripline are revealed. |
