论文摘要
预计二极管原子的电偶极力矩（EDM）对违反电荷的违规行为敏感，尤其是在核中通过核Schiff力矩敏感。我明确证明，通过考虑中性原子中核子EDM的筛选，获得了源自核子EDM的Schiff矩算子的众所周知形式。因此，对席夫力矩的额外贡献是由核素EDM与质子的相互作用引起的核EDM的筛选。在独立粒子模型中评估了$^{199} $ Hg的Schiff力矩的这种校正。
The electric dipole moments (EDMs) of diamagnetic atoms are expected to be sensitive to charge-parity violation particularly in nuclei through the nuclear Schiff moment. I explicitly demonstrate that the well-known form of the Schiff moment operator originating from the nucleon EDM is obtained by considering the screening of the nucleon EDMs in a neutral atom. Consequently, an additional contribution to the Schiff moment arises from the screening of the nuclear EDM induced by the interaction of the nucleon EDMs with the protons. This correction to the Schiff moment of $^{199}$Hg is evaluated in the independent particle model.
