Study of the Double A Hypernuclei _∧∧⁵H, _∧∧⁵He, _∧∧⁴H and _∧∧⁴He

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.
