【摘要】 本文用SU（6）对称理论讨论了四重子系统,为分析实验谱提供了一种方法。利用_ΛΛ⁴H,_ΛΛ⁴He,_Λ⁴H,_Λ⁴He和⁴He的基态是在SU（6）的同一个不可约表示中,从_Λ⁴H,_Λ⁴He和⁴He的实验资料可以求出_ΛΛ⁴H和_ΛΛ⁴He的质量。计算表明J^π=0⁺双Λ超核_ΛΛ⁴H和_ΛΛ⁴He不象有束缚态。更多还原

【Abstract】 In this paper, using SU（6） symmetry theory four-baryon system is discussed and a method of analyzing experimental spectra is provided. Because of the ground states of _ΛΛ⁴H, _ΛΛ⁴He,_Λ⁴H,_Λ⁴He and ⁴He are in the same I.R. of SU（6）, one can derives masses for _ΛΛ⁴H. and _ΛΛ⁴He from the experimental data of _Λ⁴H, _Λ⁴He and ⁴He. Calculation shows that these J^π =0⁺ double Λ hypernuclei _ΛΛ⁴H and _ΛΛ⁴He are not likely bound states.更多还原
