Abstract

Brillouin shifts of the C₁₁ mode were measured near the normal-incommensurate phase transition temperature with two scattering angles: 90 and 45 degrees. The scattering angle dependence of the Brillouin shifts is found and is inferred to be caused by the fluctuation of an order parameter.
