In phenomenological estimates (see Refs. [23,24] and references therein), the enhancement of the intrinsic nuclear Schiff moment, Ŝ , is predicted to scale with the quadrupole β 2 and the square of the octupole β 3 deformations, as well as inversely with the energy difference ∆E P D between the parity doublet Table 1 Data for selected odd-mass nuclei in the A ≈ 224 mass region exhibiting parity-doublet candidates. The table presents the isotope, its halflife T 1/2,gs , spin and parity of the ground state J π 0 , energy difference to the lowest-lying possible parity-doublet partner ∆E P D , and the lifetime T 1/2,ul of the upper level. Data are taken from the NNDC **data** base [27] and Ref. [28].
