| Abstract | Rotational bands of 252,253,254 No and the fission barriers of 254 No at spin 0¯ h and 20¯ h are calculated with the Hartree-Fock-Bogolyubov theory and the Lipkin-Nogami approximate particle number projection. The SLy4 Skyrme force is used in the particle-hole channel. A zero-range force with and without density-dependence is used in the particle-particle channel. The experimental ground state deformation (Q 20 = 32.8 b) is reproduced as well as the increase of the dynamical moment of inertia with frequency both for 252 No and 254 No. The rotational band of 253 No is also calculated. Fission barriers of 254 No at spin 0¯ h and 20¯ h show the robustness of shell-corrections against rotation in these heavy nuclei. |
