  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. While 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.
