Abstract:

The binding energies of ⁵_ΛHe, ⁹_ΛBe, ⁶_ΛΛHe and ¹⁰_ΛΛBe 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_ΛΛHe) within their experimental uncertainties lead to an overbinding of B_ΛΛ(¹⁰_ΛΛBe) and inversely B_Λ(⁵_ΛHe), B_Λ(⁹_ΛBe) and B_ΛΛ(¹⁰_ΛΛBe) to an underbinding of B_ΛΛ(⁶_ΛΛHe).
