中性原子的电偶极矩主要是由核的Schiff矩引起的。在核壳模型下计算了平均场理论之外的原子核波函数，该模型包含了违反宇称和时间反演不变性的两体相互作用。利用得到的波函数计算了氘同位素最低态的Schiff矩。本文用核的Schiff矩估计了中性原子电偶极矩的上限。
The electric dipole moment of a neutral atom is mainly induced by the nuclear Schiff moment. The nuclear wave functions beyond mean-field theories are calculated in terms of the nuclear shell model, which contains two-body interactions violating parity and time-reversal invariance. Using wave functions thus obtained, the Schiff moments for the loweststates of Xe isotopes are calculated. The upper limit for the electric dipole moment of theXe neutral atom is estimated using its nuclear Schiff moment.
