Abstract:

Binding energies of double-Λ hypernuclei 10ΛΛBe, 13ΛΛB and 6ΛΛHe are calculated on the basis of G-matrix theory in finite nuclei. The core + Λ+ Λ three-body model is adopted and the G-matrix for ΛΛ interaction is treated consistently with the model space. As the bare interaction the Nijmegen model D and model F are used. It is discussed that the consistency of the interaction with the model space is very important to calculate reliably the binding energies. It is shown that if the new event of double-Λ hypernuclei is interpreted as 13ΛΛB, model D reproduces the experimental data very well, whereas model F does not.
