摘      要：Since the discovery of the halo nucleus ^(11)Li in 1985,halo phenomena in exotic nuclei have always been an important frontier in nuclear physics *** relativistic density functional theory has achieved great success inthestudyofhalonucleg,theself-consistent description ofhalonucleusLiandthe microscopic predic tion of deformed halo *** paper introduces some recent progresses based on the deformed relativistic Hartree-Bogoliubov theory in continuum(DRHBc)and the triaxial relativistic Hartree-Bogoliubov theory in continum(TRHBc).A microscopic and self-consistent description of the deformed halo nucleus ^(37)Mg,including its small one-neutron separation energy,large root-mean-square radius,diffuse density distribution,and p-wave components for the halo neutron,has been achieved by the DRHBc *** DRHBc theory has also predicted a deformed neutron halo and the collapse of the N=28 shll closureintherecently discovered isotope ^(39)Na The TRHBc theory has been newly developed and applied to the aluminum isotopic *** heaviest odd-odd ^(42)AI has been predicted as a triaxial halo nucleus with a novel shape decoupling between its core and halo at the triaxial level.
