采用基于手征SU( 3)夸克集团模型的YN相互作用位 ,计算了轻Λ超核5 ΛHe ,4ΛHe和4ΛH的能谱 .结果显示 ,近似的等效定域ΛN相互作用位不能给出正确的超核结合能 ,而非定域ΛN位能给出超核5 ΛHe结合能的合理范围以及超核4ΛHe和4ΛH能级的正确顺序 .这表明YN相互作用的非定域性起着重要的作用 .计算中采用了 2套模型参数 ,计算结果正好给出实验值的上下限 .这表明超核的实验数据可以提供更多的信息来进一步约束YN相互作用 ,以弥补YN散射实验数据的不足 .利用超核实验数据来优化选择YN相互作用参数是有可能做得到的 .
Using the YN interaction sites based on the chiral SU (3) quark group model, the energy spectra of the light Λ hypernumbers 5 Λ He, 4 Λ He and 4 Λ H were calculated. The results show that the approximate equivalent Λ N interaction sites can not be given correctly , Whereas the non-localized ΛN sites give a reasonable range of 5 Λ He binding energies and the correct order of 4 Λ He and 4 Λ H supernuclei, indicating that the delocalization of YN interactions plays an important role The two sets of model parameters are used in the calculation and the calculation results just give the upper and lower limits of the experimental values.This shows that the experimental data of hypernuclear can provide more information to further constrain the YN interaction to make up for the lack of YN scattering experimental data It is possible to use the hypernucleus experimental data to optimize the choice of YN interaction parameters.
