Superfluid Fermi

Soft transitional nuclei are considered in a model of a finite superfluid Fermi system in the vicinity of a phase transition. Microscopic estimates are given for the limiting strength of anharmonicity in such a system. The estimates are based on collectivity, adiabaticity and quadrupole symmetry of large amplitude collective motion. The results imply the leading role of quartic anharmonicity and the O(5) dynamical symmetry of low-lying spectra. It justifies the phenomenological model suggested earlier which turned out to be quite successful in description of data.

The recent progress in the pairing problem and the superfluidity of neutron stars is reviewed. The theory of superfluidity in nuclear and neutron matter is developed beyond the BCS approximation. In particular, the dispersion effects including the depletion of the Fermi surface and the core polarization are discussed within the Brueckner theory. In addition, the effects of vertex correction to the pairing interaction, based on RPA, are incorporated in the generalized gap equation. The isospin singlet (neutron–proton) pairing is investigated in connection with the low-density crossover from a superfluid Fermi system to a Bose–Einstein condensate and the isospin suppression of pairing in neutron-rich matter. The onset of different superfluid states of neutron–neutron and proton–proton pairing in neutron stars is discussed in the context of application to rotational motion and cooling process.
