Abstract

Octupole deformation results in a strongly enhanced collective Schiff moment in Th229 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 Σ1 state and in the metastable Δ13 state of diatomic molecule ThO229. Similar enhancements exist in molecular ions ThOH+229, ThF+229, and RaOH+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.
