Rotating deformed halo nuclei

Deformed halo is one of the most notable exotic nuclear structures. The deformed relativistic Hartree-Bogoliubov theory in continuum (DRHBc) has been developed and achieved self-consistent descriptions of deformed halo nuclei by including deformation and continuum effects. The DRHBc theory has been used to study the ground states of deformed halo nuclei and predict an interesting phenomenon, the shape decoupling between the core and the halo. In this contribution, the implementation of the angular momentum projection technique based on the DRHBc theory and its application in rotationally excited deformed halo nuclei are briefly presented. It has been shown that the halo structures and shape decoupling effects also exist in the low-lying rotational states of deformed halo nuclei. (author)
