摘要
The discovery of Be has aroused many researchers’ interest in studying double ∧ hypernuclei. In general, they use a variational method, and choose a phenomenological potential to diseuss the 3-body He(α-∧-∧) or 4-body Be (α-α-∧-∧) problems. Their results can explain the double ∧ hypernuclei He and Be observed in experiments. Up to now, H has not been found in experiment.
