Advances in neutron technology made during the past decade have permitted neutron inelastic scattering experiments to be performed with full polarization analysis. The power of this technique for the identification of components of dynamic spin fluctuations in magnetic systems is illustrated in this presentation by two experiments on the one-dimensional, X-Y antiferromagnet TMMC. In one experiment, spin fluctuations due to ..pi..-solitons were measured for the first time and information was obtained on soliton-soliton collision processes. In the other, a theory which apparently described finite-energy magnetic excitations measured with unpolarized neutrons was shown to be deficient. Both of these experiments were carried out at the Institut Laue-Langevin in Grenoble, France. 13 refs., 8 figs.
