EnhancedT-Nonconserving Nuclear Moments

$T$- and $P$-nonconserving nuclear moments induced by a parity- and $\mathrm{CP}$-nonconserving interaction in the QCD Lagrangian are discussed. The mixing of nearly degenerate opposite-parity ground-state doublets in certain deformed nuclei leads to electric dipole and magnetic quadrupole moments ${10}^1$-${10}^3$ and ${10}^3$-${10}^4$ times larger, respectively, than those generated by the unpaired valence nucleon.
