  Nuclei with static intrinsic octupole deformation or a soft octupole
vibrational mode lead to strongly enhanced collective nuclear Schiff? moments.
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.
Nuclear octupole deformations are predicted in many short lived isotopes. This
paper investigates octupole deformations in stable and very long lifetime
nuclei such as 153Eu, 235U, 237Np and 227Ac, which can ease atomic experiments
substantially. The estimates of the enhanced Schiff? moments, atomic electric
dipole momentsand T, P-odd interaction constants in molecules containing these
nuclei are presented.
