Alpha Cluster Structure of Hypernuclei and Λ-Seperate Energy of Λ17O

  • By using the alpha cluster structure model of hypernuclei and the phenomenological interaction potential between Λ hyperon and α-particle, the Λ seperate energy of the hypernucleus 13ΛC is calculated. A good agreement with the experimental data is achieved. Based on this the Λ-seperate energy of the hypernucleus 17ΛO is predicted. It is consistent with the empirical value of 17ΛO and advantages over the existing theoretical calculation made up-to-date.

Abstract: By using the alpha cluster structure model of hypernuclei and the phenomenological interaction potential between Λ hyperon and α-particle, the Λ seperate energy of the hypernucleus 13ΛC is calculated. A good agreement with the experimental data is achieved. Based on this the Λ-seperate energy of the hypernucleus 17ΛO is predicted. It is consistent with the empirical value of 17ΛO and advantages over the existing theoretical calculation made up-to-date.
