Modeling of 6 hypernucleus within configuration space Faddeev approach
Abstract
The cluster 4 He++ n model is applied to describe the 6 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 n interaction and the phenomenological potentials for the α and α 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.
