QRPA Calculation in Fitting Process of

Functional

J. Terasaki and J. Engel

Proposal:

• Use energies and B(E2)↑’s of lowest 2+ states in even-

even nuclei.

There are more than 500 measured energies and about half that many measured

  BE2's.  These data reflect presence of dynamical deformation as well as   static deformation.

• Use Gamow-Teller resonances and higher-multipole analogs

(e.g. spin-dipole) for time-odd properties

Not as much data, but still very useful, particularly once deformed QRPA   is available.
