Toroidal structure of super-heavy nuclei in the HFB theory

Toroidal structure of super-heavy nuclei has been analyzed within the Hartree-Fock-Bogoliubov theory with the Gogny D1S force. The global minimum of the potential energy of systems with Z > 130 has been found for nuclei in the shape of a torus. The binding energy of toroidal super-heavy nuclei is lower than the energy of the spherical nuclei by 180 MeV.
