Core-Polarization Contribution to the Nuclear Anapole Moment

Abstract

The importance of core contributions to the anapole moment in nuclei is examined. A model of the core-polarization correction is presented. The model is based on the coupling of the valence particles to the spin-dipole $J=1^{-}$ giant resonances of the core. A shell-model calculation of this correction is presented. The single-particle moments are calculated with Woods-Saxon and Skyrme Hartree Fock radial wave functions, and the general issues associated with nuclear configuration mixing are discussed.
