Abstract
Raleigh and MandelshtamBrillouin light scattering has been investigated in chalcogenide glasses of the As2S3xI1−x system for x = 100−080 Longitudinal hypersound velocities adiabatic elastooptical constants p12ad at frequencies of ∼15 GHz and LandauPlaczek ratios RLP are found and scattering losses are calculated Significant iodine additives are shown to result in the appearance of different features in the behavior of concentration dependences of the investigated parameters
