Enhanced nuclear Schiff moment in stable and metastable nuclei

Octupole deformation results in strongly enhanced collective nuclear Schiff moments. In nuclear isotopes which are neighbours to the nuclei with the static octupole there is a soft octupole vibration mode which also leads to the enhancement of the Schiff moment. These mechanisms produce enhanced Schiff moments in stable and very long lifetime nuclei such as 153Eu, 235U and 237Np. Interaction between electrons and these Schiff moments produce enhanced time reversal (T) and parity (P) violating electric dipole moments (EDM) in atoms and molecules. Corresponding experiments may be used to test CP-violation theories predicting T,P-violating nuclear forces and to search for axions.
