• 論文の詳細を見る

• The binding energies of ^5_ΛHe, ^9_ΛBe, ^6_<ΛΛ>He and ^<10>_<ΛΛ>Be hypernuclei are evaluated within the framework of the microscopic α-cluster model and with special attention to the ΛN exchange force effect. The ΛN exchange force, which contributes in different ways for He and Be hypernuclei, is an important ingredient for the attempt at consistent reproduction of the four binding energies. Yet the ΛN and ΛΛ interactions which reproduce the observed B_Λ(^5_ΛHe), B_Λ(^9_ΛBe), and B_<ΛΛ>(^6_<ΛΛ>He) within their experimental uncertainties lead to an overbinding of B_<ΛΛ>(^<10>_<ΛΛ>Be) and inversely B_Λ(^5_ΛHe), B_Λ(^9_ΛBe) and B_<ΛΛ>(^<10>_<ΛΛ>Be) to an underbinding of B_<ΛΛ>(^6_<ΛΛ>He).
