On the basis of the MT I-III model, the ΛΛ interaction potential is specified in the form VΛΛ = 2 3VNN. Phenomenological potentials are used to describe Λα and αα interactions. The binding energies of the ΛΛ6He and Λ9Be hypernuclei and the parameters of low-energy Λ-hyperon and α-particle scattering on a Λ5He hypernucleus are calculated. It is shown that the proposed ΛΛ interaction potential makes it possible to reproduce faithfully the binding energy of the ΛΛ6He hypernucleus and that scattering in the ΛΛ5He system is similar to neutron scattering on a deuteron.
