Abstract
Measurements of the acoustical attenuation and sound velocity in amorphous polystyrene down to 0.37 K are reported. The frequency range is from 15 to 190 MHz. At the lowest temperatures, the velocity exhibits the logarithmic temperature dependence usual in amorphous materials, but the attenuation does not reveal the expected lawKeywords
