Acoustic Attenuation in Crystalline Carbon Tetrachloride

Abstract
The acoustic attenuation in crystalline carbon tetrachloride has been measured using an experimental technique that precludes handling or cutting of the crystals. The measured attenuation was found to be twice the value predicted by the resonance-absorption theory. It is observed that the relaxation rates in liquid and solid carbon tetrachloride are of the same order of magnitude, the attenuation in the liquid being approximately twice that in the solid.
