讨论了QCD拉格朗日中由宇称-和cp -非守恒相互作用引起的T-和p -非守恒核矩。在某些变形核中,几乎简并的对宇称基态偶极子的混合导致电偶极子和磁四极子矩分别比未配对的价核子产生的矩大10/sup 1/—10/sup 3/和10/sup 3/—10/sup 4/倍。
T- and P-nonconserving nuclear moments induced by a parity- and 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/sup 1/--10/sup 3/ and 10/sup 3/--10/sup 4/ times larger, respectively, than those generated by the unpaired valence nucleon.
