首次计算了原子团簇模型中同向量电荷共轭-宇称(CP)-奇π交换核力产生的电偶极矩(EDM)，较好地描述了原子核的低激发态结构。结果表明，EDM与中子EDM和同向矢量CP-奇核耦合的关系是线性的。由于态与对宇称()态结构的不同，CP-奇核耦合的线性增强因子小于氚核的线性增强因子。我们阐明了该结构在增强电火花加工中所起的作用。这一结果为寻找其他具有较大增强因子的原子核提供了良好的指导原则。我们还提到了EDM在确定超越标准模型的新物理中的作用。
We calculate for the first time the electric dipole moment (EDM) ofgenerated by the isovector charge conjugation-parity (CP)-odd pion exchange nuclear force in the-cluster model, which describes well the structures of low-lying states of thenucleus. The linear dependence of the EDM ofon the neutron EDM and the isovector CP-odd nuclear coupling is found to be. The linear enhancement factor of the CP-odd nuclear coupling is smaller than that of the deuteron, due to the difference of the structure between thestate and the opposite-parity () states. We clarify the role of the structure played in the enhancement of the EDM. This result provides good guiding principles to search for other nuclei with large enhancement factor. We also mention the role of the EDM ofin determining the new physics beyond the standard model.
