Structure of S=-2 hypernuclei at J-PARC
Energy levels of the double-A hypernuclei, 7ΛΛHe,7ΛΛLi, 8ΛΛLi, 9ΛΛLi, 9ΛΛBe and 10ΛΛBe are discussed. Interactions between the constituent particles are determined so as to reproduce reasonably the observed low-energy properties of the α + x nuclei, x + Λ,α+x+Λ and α+Λ+Λ systems. With no adjustable parameters for the α+x+Λ+Λsystem, BΛΛ of ground and bound excited states of the double-A hypernuclei with A =7-10 are calculated using Gaussian Expansion Method. Furthermore, the fourbody caluclation of 4ΛΛH and NNN(E) were peformed. The ΛΛ-(E)N coupling was very important in making 4ΛΛH bound.
