我们在三体模型的基础上，用微观波函数研究了结构。在三体模型的生成元坐标法计算中，合理地描述了、的能谱和态以及态的谱。在双核子图像的基础上，讨论了自旋-轨道力对双核及其对的影响.态中的偶获得涉及偶中奇宇称混合的自旋轨道势能。宇称混合的自旋-轨道势能增益对于处于态的对子来说并不是很有效。偶中的宇称混合被认为是偶在核表面的自旋轨道势中的内部对称性破缺。
We investigate the structure ofwith the microscopic wave function based on the three-bodymodel. In the calculation of the generator coordinate method of the three-body model,energy spectra of, andstates andspectra ofstates inare described reasonably. Based on the dinucleon picture, the effect of the spin-orbit force on theandpairs around thecore is discussed. Thepair in thestate gains the spin-orbit potential energy involving the odd-parity mixing in the pair. The spin-orbit potential energy gain with the parity mixing is not so efficient for thepair in thestate. The parity mixing in the pair is regarded as the internal symmetry breaking of the pair in the spin-orbit potential at the nuclear surface.
