摘要：

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