The VV scatterins srectra in the ab nlane were measured with various scat..terin: angles. It is shown that the elastic stiffness constant C66 snows ctear dis-r>ersion near the transition temr>erature Tt. Just in the freczuencv region of GHz.A dynamic central peak (DCP) was observed in the spectra of quasitransverseacoustic phonon near q//[100] in the very vicinity of T... From the observedangular dependence of the Iinewidth of DCP it is revealed that this central peakscattering is caused by the piezoelectric interaction between the z-component ofthe polarization fluctuation and the xy shear component in the quasitransversephonon.
