Polarization associated with the coupling to isoscalar dipole compression mode - art. no. 024318

The effect of core polarization on isoscalar dipole one-particle moments du e to the coupling with isoscalar giant dipole resonance (compression mode) is estimated. Numerical calculations with the core nucleus Pb-208(82)126 sh ow that a small enhancement of one-particle moments is obtained, of which t he magnitude depends sensitively on relevant one-particle orbitals. The res ults are important for a microscopic understanding of the electric dipole m oments (Schiff moments) measured for nuclei in this mass region.
