在α原子团簇模型中，首次计算了同向量CP-奇π交换核力产生的C的电偶极矩，较好地描述了C核的低能态结构。结果表明，C的EDM与中子EDM和等向量CP-奇核耦合的线性关系为d13
M C}=-0.33d_n-0.0012 Ar G_pi^{(1)}$。由于$1/2^-1$态和相反的宇称($1/2^+$)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C的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) of $^{13}$C generated by the isovector CP-odd pion exchange nuclear force in the $alpha$-cluster model, which describes well the structures of low lying states of the $^{13}$C nucleus. The linear dependence of the EDM of $^{13}$C on the neutron EDM and the isovector CP-odd nuclear coupling is found to be $d_{^{13}{
m C}} = -0.33 d_n - 0.0012 ar G_pi^{(1)}$. 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 the $1/2^-_1$ state and the opposite parity ($1/2^+$) 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 of $^{13}$C in determining the new physics beyond the standard model.
