Detailed inelastic neutron scattering measurements have yielded the behavior of the scattering functionS(q, &ohgr;) for both the transverse and the longitudinal fluctuations throughout the critical region of the uniaxial antiferromagnet MnF2. The results are discussed in the light of the theory of dynamic scaling. The results belowTNare discussed with reference to quasihydrodynamic theories of the spin fluctuations in the ordered state.
