✦ Synopsis

Configuration space Faddeev calculations are performed for the binding energy of 6 ΛΛ He and 9 Λ Be bound states, here considered as αΛΛ and ααΛ clusters respectively, in order to study the dependence of the calculated binding energy on the αΛ potential input. For 6 ΛΛ He, using realistic interactions, the uncertainty in extracting the ΛΛ 1 S 0 interaction strength does not exceed 0.1 MeV, which is a fraction of the order of magnitude derived for other theoretical uncertainties. For 9 Λ Be, the dependence of the calculated binding energy on the αΛ potential is considerably larger, of order 1 MeV. Our results for 9 Λ Be suggest that the odd-state αΛ interaction is substantially reduced with respect to the even-state component.
