摘　　要：Variational Monte Carlo calculations are carried out for _(ΛΛ)^(4)H to explore the possibility of its existence,using realistic NN,NNN,and phenomenologicalΛN andΛNN interactions.We also perform calculations using FGNNand NSC97ΛN potentials,and demonstrate the effect of the exchange part of the two-bodyΛN interaction and three-bodyΛNN interaction on the binding energy ofΛΛ4H.Still the stability of _(ΛΛ)^(4)H remains an open question and this hypernuclear system has to be explored more theoretically.
