在 J-PARC 进行的乳液计数器混合实验中，观察到吸收事件衰变成孪生单超核。运动学计算能够对反应过程进行独特的识别。对于系统中超子的结合能，推导出值 。的能级可能是核态，表明弱耦合。
In an emulsion-counter hybrid experiment performed at J-PARC, aabsorption event was observed which decayed into twin single-hypernuclei. Kinematic calculations enabled a unique identification of the reaction process as. For the binding energy of thehyperon in thesystem a value ofwas deduced. The energy level ofis likely a nuclearstate which indicates a weakcoupling.
