Abstract：
In this paper, double Λ binding energies B _ΛΛs of _ΛΛ ⁵He( _ΛΛ ⁵H), AA4He and _ΛΛ ⁴H are calculated with the help of few-body models. The results show that stable binding state for _ΛΛ ⁵H or _ΛΛ ⁵He exists definitely with B _ΛΛ( _ΛΛ ⁵H)=6.75MeV and B _ΛΛ( _ΛΛ ⁵He)=7.67MeV,respectively. As to _ΛΛ ⁴He and _ΛΛ ⁴H, preliminary results indicate that _ΛΛ ⁴H is unstable against decaying into Λ+ _Λ ³H, and _ΛΛ ⁴He has no binding state.
