Properties of super-heavy elements in Hartree-Fock-Bogolubov model with the Gogny force. M. Warda Katedra Fizyki Teoretycznej, Uniwersytet Marii Curie-Skłodowskiej, Lublin, Poland, J. Egido, L. Robledo Departamento de Física Teórica C-XI, Universidad Autónoma de Madrid, Madrid, Spain.
Motivation • Recent progress in synthesis of super-heavy elements (Dermstedt, Dubna, RIKEN) • Good results of Hartree-Fock-Bogolubov theory with the Gogny force in trans-fermium nuclei • D1S Gogny force • Imposed axial symmetry • Ground state properties (deformations, α decay) • Fission barriers XII Nuclear Physics Workshop, Kazimierz Dolny 2005

Conclusions • Properties of the super-heavy nuclei are well described by the Gogny force calculations. • Results are in consistence with the other models and with available experimental data. • The magic numbers are deduced at N=162 (deformed ground state) and at N=182 (spherical ground state). • The isotones beyond N=184 have got octupole deformation. • Following results of α decay and spontaneous fission barriers the super-heavy nuclei around N=180 have the highest half-lives. • Triaxial deformations should be included.
