Assignment of an Anomalous Peak in the Brillouin Spectrum of Oriented Polymer Films.

Abstract

The origin of a previously unassigned peak in the Brillouin spectrum of an oriented polymer film has been clarified. This peak is shown to be due to backscattering from a quasitransverse acoustic phonon from the reflected laser beam. Studies of this peak are expected to provide the information concerning the birefringence effect of the oriented film. (Author)
