一个基本粒子的永久电偶极矩的存在意味着违反时间反转不变性。反磁性中性原子的电偶极矩主要由核席夫矩引起。本文利用壳模型波函数计算了不同Xe同位素的相互作用引起的违反宇称和时间反转不变性的希夫矩。单粒子和单空穴激发对希夫矩的贡献在不同轨道上是不同的。同时发现，岩心激励的贡献大于其他粒子-空穴的贡献。
The existence of the permanent electric dipole moment of a fundamental particle implies violation of time reversal invariance. The electric dipole moment of a diamagnetic neutral atom is mainly induced by the nuclear Schiff moment. In this study the Schiff moments induced by the interaction which violates parity and time reversal invariance are calculated for various Xe isotopes using the shell-model wave functions. The contributions to the Schiff moment from one-particle and one-hole excitations turn out to be very different from orbital to orbital. It is also found that the contributions from the core excitations are larger than other particle-hole contributions.
