【 摘 要 】

We review interesting phenomena of hypernuclear structure from view points of clustering physics. The glue like role of Λ particle provide with size contraction of hypernuclei. For an example, we review the structure ofΛ7Li,Λ13C. As an example, the energy gain by the addition of a Λ particle is dependent on the shell-like states or clustering states in core nuclei, we review the structure of12C andΛ13C. We show a very preliminary result ofΛ6H within the framework of5H + n + n + Λ four-body cluster model to demonstrate the stabilization of the state due to the attraction of ΛN interaction. Finally, we review the structure of double Λ hypernucleus,ΛΛ11Be with the αα + Λ + Λ + n five-body cluster model.
