Abstract

The cluster 4He+Λ+n^4\rm He+\Lambda+\rm n model is applied to describe the Λ6^6_\LambdaHe hypernucleus. The consideration is based on the configuration space Faddeev equations for a system of non-identical particles. A set of the pair potentials includes the OBE simulating (NSC97f) model for the Λn\Lambda \rm n interaction and the phenomenological potentials for the αΛ\alpha\Lambda and αn\alpha \rm n interactions. We calculated energies of spin (1^-,2^-) doublet. For the 2^- excitation energy, the obtained value is 0.18 MeV. The hyperon binding energy of the bound 1^- state is less than the experimental value, which may be an evidence for violation of the exact three-body cluster structure.
