Superdeformed oblate superheavy nuclei

We study stability of superdeformed oblate (SDO) superheavy Z >= 120 nuclei predicted by systematic microscopic-macroscopic calculations in 12D deformation space and confirmed by the Hartree-Fock calculations with the SLy6 force. We include into consideration high-K isomers that very likely form at the SDO shape. Although half-lives T-1/2 less than or similar to 10(-5) s are calculated or estimated for even-even spin-zero systems, decay hindrances known for high-K isomers suggest that some SDO superheavy nuclei may be detectable by the present experimental technique.
