Sažetak
The Λ7He hypernucleus is considered within the Λ5He + n + n cluster model. The hyperon—nucleon interaction is described by a one-boson-exchange potential that is constructed on the basis of the NSC97f model. Phenomenological potentials are used to describe the αΛ and αN interactions. For the Λ5Hen interaction, use is made of the folding-model potential. The calculations of the hyperon binding energy in the ground state of the Λ7He hypernucleus on the basis of Faddeev equations in configuration space yield a result (5.35 MeV) that agrees well with preliminary experimental data (5.4 MeV). The problem of calculating the hyperon binding energy within the three-body approach is discussed. In calculating the energy spectrum of Λ7He, use is made of a version of the method of analytic continuation in the coupling constant. Low-lying excited states of this nucleus can be classified as an analog of the corresponding states of the 6He nucleus with allowance for the clustering of the Λ5He+n+n system in the 6He(J π)+Λ(s) form.
