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.
