Effects of core polarization on the nuclear Schiff moment

Schiff moments were calculated for a set of nuclei with full account of core polarization effects. A finite range P- and T-violating weak nucleon-nucleon interaction has been used in the calculations. Although in the absence of core polarization the Schiff moment depends on one combination of the weak interaction constants, in the presence of core polarization the Schiff moment depends on all three constants separately. The dominant contribution comes from isovector, $\Delta T=1$, part of the weak interaction. The effects of core polarization were found to have in general a large effect on the Schiff moments.
