Netrtron inelastic scattering experiments on the near-percolating Hesisenberg axntiferroraaagnet,RbNIng.3g]VIgg.?jF3, were perf'ortaaed trsirug a high energy-resolution spectrottaeter (15 7v.eV). Therestults reveal a crossover f'roraa l11dgl1OI1 excitations at staaall w'ave-vectors to over-datnped f'ractonexcitations at large xvave-vectors. This exzinces experimentally that the atomic connectivity inan infinite percolatizag network looks hotnogeneotrs at wave-vectors srnaller than a crossoverwave-vector. as predicted by the theory.
