Abstract
Temperature dependence of ultrasonic attenuation is investigated for potassium halides in the temperature range 100-400Â K. These calculations are done for KCl, KBr and KI for longitudinal and shear waves along the ã1Â 1Â 1ã direction. The non-linearity coupling parameters and thermal relaxation time have also been obtained for these crystals. In the present investigation, it has been found that phonon-phonon interaction is the dominant cause for ultrasonic attenuation.
