Abstract：
With the aid of the theoretical few-body method, the binding energies of the double ∧ hypernuclei _∧∧ ⁵H, _∧∧ ⁵He, _∧∧ ⁴H and _∧∧ ⁴He are calculated. The results show that a stable bound state of _∧∧ ⁵H or _∧∧ ⁵He exists definitely with the double ∧ binding energies B _∧∧( _∧∧ ⁵H)=6.75MeV, and B _∧∧( _∧∧ ⁵H)=7.67MeV, respectively. As to _∧∧ ⁴H, the preliminary results manifest that it has a bound state but unstable against the decay to the _∧ ³H+∧ channel. No bound state exists for _∧∧ ⁴He.
