The topics covered by this talk could be boldly summarized in another way by asking the question: to describe accurately intrinsic vortical currents due to pairing correlations, do we need Routhian Hartree-Fock-Bogoliubov calculations?

Collective gyromagnetic ratios g{sub R}, microscopically calculated from Hartree-Fock plus BCS calculations using the SkM{sup {asterisk}} force, are found to be very different from the rough Z/A estimates. It is pointed out that the latter disagree w

The fission barriers of twenty-six isotopes of Thorium, Uranium, Plutonium, Californium, Fermium and Nobelium have been microscopically calculated up to and beyond the second saddle point within a constrained Hartree-Fock plus pairing approach. The S

The present paper establishes a link between pairing correlations in rotating nuclei and collective vortical modes in the intrinsic frame. We show that the latter can be embodied by a simple S-type coupling a la Chandrasekhar between rotational and i
