Abstract

New Faddeev-Yakubovsky calculations are reported for ΛΛ6He and ΛΛ10Be in terms of clusters of α's and Λ's, using ΛΛ s-wave potentials motivated by several of the Nijmegen model interactions. The self consistency of the ΛΛ hypernuclear world data for these species is discussed. The newly reported ΛΛ6He event is found to be compatible with ΛΛ interaction strengths provided by the Nijmegen soft-core one-boson-exchange model NSC97. Faddeev calculations for ΛΛ5H and ΛΛ5He suggest that these ΛΛ hypernuclei are stable against emitting Λ's for any (essentially attractive) ΛΛ interaction, whereas calculations for ΛΛ4H do not allow a clear-cut conclusion whether or not it is particle stable.
