9. Extension to isotones (I2 term (Yamagami) + Two-body Coulomb)
Universal Pairing Density Functional with Isospin Dependent Pairing
To be clarified
Extension to isotones (I2 term (Yamagami) + Two-body Coulomb)
IS+IV pairing interaction looks promising for the fitting purpose.
Can pairing correlation properties be isolated from the full
functional? 9 9

10. Summary
Core Polarization Effect in Finite Nuclei still needs to be clarified.
Isospin dependent interaction is applied to describe the pairing properties of
finite nuclei successfully.
Toward universal pairing density functional.
