We investigate roles of the tensor force (TF) on the pairing correlations in the ground-state structure of ${}^{12}\mathrm{C}, {}^{16}\mathrm{O}, {}^{20}\mathrm{Ne}$, and ${}^{32}\mathrm{S}$ nuclei within a deformed BCS model. For pairing matrix elements, we exploit the Brueckner $G$ matrix derived from the charge-dependent Bonn potential. In particular, the isoscalar (IS) neutron-proton ($np$) pairing is studied in detail in relation to spin-triplet even TF in the nucleon-nucleon interaction. Detailed analyses of the $np$ pairing and possible enhancement of the IS channel are performed by focusing on roles of attractive spin-triplet even and repulsive spin-triplet odd channels in the TF for the ground states of the nuclei with some deformation. It is also shown that the TF may play a crucial role of properly interpreting the experimental data of a two-nucleon knockout reaction from ${}^{12}\mathrm{C}$.

C12、O16、Ne20和S32原子核基态张量力的等标配对相关性

我们研究了张量力（TF）对基态结构中配对相关性的作用 ${}^{12}\mathrm{C}, {}^{16}\mathrm{哦}, {}^{20}\mathrm{ne}$， 和 ${}^{32}\mathrm{秒}$变形的 BCS 模型中的原子核。对于配对矩阵元素，我们利用 Brueckner$G$从电荷相关的波恩电位导出的矩阵。特别是，等标量 (IS) 中子-质子 ($n磷$) 对与核子-核子相互作用中的自旋-三重态甚至 TF 相关的配对进行了详细研究。详细分析$n磷$IS 通道的配对和可能的增强是通过关注 TF 中有吸引力的自旋-三重偶数和排斥性的自旋-三重态奇数通道对于具有一些变形的原子核的基态的作用来进行的。还表明，TF 可能在正确解释双核子敲除反应的实验数据方面发挥关键作用${}^{12}\mathrm{C}$.
