Shape coexistance of octupole shapes in the superheavy nucleus

We discuss recent applications of covariant density functional the­ory to the investigation of the full deformation space of the superheavy nucleus 286No. The calculations were performed on a three-dimensional lattice in a mi­croscopic and self-consistent manner. For the ground state of 286No, we find a novel pure non-axial octupole shape. This state coexists with a tetrahedral isomeric state at an excitation energy of 0.12 MeV.
