Magnetic inelastic scattering of neutrons from a Heisenberg magnet RbMn_0.15Mg_0.85F₃, whose Mn concentration is far below the percolation threshold, has been studied. The observed incoherent inelastics spectrum reveals five peaks which correspond to the intracluster transition energies of isolated two-spin cluster.
