A new prediction for the binding energy of the 7λHe hypernucleus

P-shell A = 7 hypernuclei are considered in the cluster 5λHe + N + N model. The folding procedure using the OBE simulating (NSC97f) model for ΛN potential and various αλ potentials are applied to construct the 5λHe-N interaction. Configuration space Faddeev calculations are performed for the hyperon binding energy of the 7λHe(1/2+) and 7λLi(1/2+ and 3/2+, T = 0) hypernuclei. The new predicted value for Bλ(7λHe) is 5.35 MeV. This value was obtained with the 6λHe(2-) excitation energy equal to 0.26 MeV. Since the 2- state of 6λHe has not yet been observed, the 6λHe(2-) excitation energy was chosen to reproduce the experimental value of the 7λLi(3/2+) excitation energy by the adjustment of the 5λHe-N effective potential
