我们建议在不改变其自旋-同位旋结构的情况下，通过两个系统的能级来获得相互作用的自旋-同位旋依赖信息。利用高斯展开法和晶格QCD计算得到的最先进势，发现在同位旋三重态和单重态通道中都存在自旋双重态束缚态。在等三重态和等单重态之间的自旋双重态反转被发现与通道中相互作用的相对强度有很强的相关性。提出了目标上的反应来产生这些束缚态。
We propose to obtain information on the spin-isospin dependence of theinteraction through the energy levels ofandsystems, withbeing a spectator to attract thepair without changing its spin-isospin structure. By using the Gaussian expansion method with the state-of-the-artpotential obtained from lattice QCD calculations, it is found thathas spin-doublet bound states withandin both isospin triplet and singlet channels. The inversion of thespin-doublet between the iso-triplet and the iso-singlet is found to be strongly correlated with the relative strengths of theinteraction in the, andchannels. Theandreactions on thetarget are proposed to produce those bound states.
