| Popis: | The results of measurements of ordinary third sound attenuation at T=1.35 K are reported. The attenuation is measured by using a continuous wave technique for frequencies up to 40 kHz. We find that for helium film thicknesses in the regime 5.09≤d≤9.90 layers the attenuation of third sound increases both with frequency and film thickness. We discuss our results in the context of previous work in this area. |
