ensity functional for description of novel pairing properties in nuclei far from stability

Toward a universal description of pairing correlations in nuclei
far from stability, we extend the energy density functional (DF)
by enriching the density dependence of the isoscalar and isovector
couplings in the particle-particle channel (pair-DF).

In this seminar, I emphasize the necessity of the quadratic
isovector density term in addition to the linear terms for
reproducing the asymmetry parameter (N-Z)/A dependence of
pairing correlations. The coupling constants in the pair-DF
are optimized by the extensive Hartree-Fock-Bogoliubov calculation
with Skyrme-type DF for the particle-hole channel. The performance
of our pair-DF will be discussed in detail.
