Abstract
The attenuation of Rayleigh waves in quartz was measured as a function of temperature from 4.2 to 100 °K and frequency from 300 to 2000 MHz. Below 20 °K, the attenuation was observed temperature‐independent. From 20 to 40 °K, the results were consistent with a three‐phonon interaction process varying as T4 but with little or no dependence on frequency. Above 40 °K, the attenuation showed a lower dependence on temperature than T4 and oscillated due to an interference effect between the Rayleigh wave and a bulk wave generated at the same time.Keywords
