    The inelasticity of the critical scattering of neutrons in terbium has been measured above the Neél temperature at the (0, 0, 2−Q) satellite position. The results show that dynamic slowing down of the fluctuations does occur in a second‐order phase transition in agreement with the general theory. However, the detailed variation of the inelasticity with temperature is in disagreement with existing theories, and it is concluded that the conventional theory is invalid except at infinite temperatures. © 1968 The American Institute of Physics
