The magnetic excitations in the chain direction of an S=2 Heisenberg antiferromagnetic chain, CsCrCl3, were measured at 20, 50, 80 and 120, K above the three-dimensional ordering temperature (TN=16, K) by inelastic neutron-scattering experiments. The dynamical scattering function at the temperatures used in the present study was found to be well described by a classical one-dimensional Heisenberg model.
