摘要：

New Faddeev-Yakubovsky calculations are reported for He-6(LambdaLambda) and Be-10(LambdaLambda) in terms of clusters of alpha's and Lambda's, using LambdaLambda s-wave potentials motivated by several of the Nijmegen model interactions. The self consistency of the LambdaLambda hypernuclear world data for these species is discussed. The newly (6)(LambdaLambda) He event is found to be compatible with LambdaLambda interaction strengths provided by the reported the Nijmegen soft-core one-boson-exchange model NSC97. Faddeev calculations for H-5(LambdaLambda) and He-5(LambdaLambda) suggest that these LambdaLambda hypernuclei are stable against emitting Lambda's for any (essentially attractive) LambdaLambda interaction, whereas calcualtions for H-4(LambdaLambda) do not allow a clear-cut conclusion whether or not it is particle stable.
