dc.description.abstractEnThe reduction of the moments of inertia (MoI) in well deformed nuclei from their rigid body values has been one of the reasons leading Bohr, Mottelson and Pines to propose the description of low-energy nuclear states by BCS-type wavefunctions. This quenching has latter been understood by Mottelson and Valatin in terms of a collective coupling of intrinsic and global rotation modes. In this paper, we review a quantitatively very satisfactory account of this coupling in the framework of so-called Chandrasekhar's S-ellipsoid velocity fields. Another experimental fact at the origin of the BCS wavefunction proposal is the systematic odd-even staggering (OES) of masses observed between odd-A and even-even nuclei. Through a simple self-consistent description of these masses we have shown that with the same parametrization of the residual interaction V_res one is able to reproduce very well both the MoI and OES effects.
