Abstract：
In this paper, double Λ binding energies B_ΛΛ s of _ΛΛ⁵He(_ΛΛ⁵H), AA4He and _ΛΛ⁴H are calculated with the help of few-body models. The results show that stable binding state for _ΛΛ⁵H or _ΛΛ⁵He exists definitely with B_ΛΛ(_ΛΛ⁵H)=6.75MeV and B_ΛΛ(_ΛΛ⁵He)=7.67MeV,respectively. As to _ΛΛ⁴He and _ΛΛ⁴H, preliminary results indicate that _ΛΛ⁴H is unstable against decaying into Λ+_Λ³H, and _ΛΛ⁴He has no binding state.
