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

Show affiliationsP-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 
and 
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 
excitation energy by the adjustment of the 5ΛHe–N effective potential. Our results are compared with those of Hiyama et al (1996 Phys. Rev. C 53 2075; 1999 Phys. Rev. C 59 2351).
