  2. Isospin dependent Pairing Interaction J.Margueron, HS and K. Hagino PRC76,064316(2007) and PRC77,054309(2008)

  3. M.Stoitsov, HFB (preliminary)

  4. Isospin Dependent Pairing Preliminary

  5. No free parameters!

  6. 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

  7. 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.

  8. Preliminary M.Stoitsov, H.F.Lu
