Isotope shifts in finite nuclei and pairing properties of nuclear matter
PACS: 21.60.+f
A uniform nuclear matter with s-wave pairing is studied within the local energy-density functional approach incorporating a few parameter sets extracted from the analysis of isotope shifts in finite nuclei. The dilute limit when the regime changes from weak to strong pairing is considered in detail, and, in strong coupling, the ground state properties of that system are found to be completely determined in leading order by the singlet scattering length a„„. The density-dependent contact pairing interaction and energy cutoff adjusted to produce a realistic value of ann is shown to be a preferable choice between the deduced parameter sets.
