| dc.description | An analysis is presented of the anomalous frequency shift and linewidth of Brillouin scattering in K<sub>2</sub>SeO<sub>4</sub> near the normal-incommensurate phase transition at T<sub>i</sub>=130 K. Fluctuations are included up to second order, which allows incorporation of the regime above T<sub>i</sub>. Below T<sub>i</sub>, terms to second order in the fluctuations and a bilinear part in the order parameter and the fluctuations each contribute significantly to the anomalies. Results for relaxation times and coupling parameters are compared with findings from other sources. |
