Enhanced nuclear Schiff moment and time-reversal violation in 229Th-containing molecules

Octupole deformation results in a strongly enhanced collective Schiff moment in Th-229 nucleus. An additional enhancement of time-reversal (T) and parity- (P) violating effects (such as T,P-violating electric dipole moments) appears in the ground (1)Sigma state and in the metastable (3)Delta(1) state of diatomic molecule (ThO)-Th-229. Similar enhancements exist in molecular ions (ThOH+)-Th-229, (ThF+)-Th-229, and (RaOH+)-Ra-225,223. Corresponding experiments may be used to test charge conjugation and parity (CP)-violation theories predicting T,P-violating nuclear forces and to search for axions.
