The λΛ interaction and the reaction Xi^- + d to n + Λ + Λ

The $\Lambda\Lambda$ interaction resulting from the SU(3) rotation of the S-wave component of the Nijmegen OBE potential $D$ is used to calculate the binding energy of $^{ 6}_{\Lambda\Lambda}$He as a $\Lambda\Lambda\alpha$ three-body system, and the neutron differential energy spectrum for the reaction $\Xi^- + d \to n + \Lambda + \Lambda$.
