Low Temperature Ultrasonic Attenuation and Velocity Studies in Metals.

Abstract

The attentuation of a high frequency sound wave in a pure metal at low temperatures is dominated by the interaction of the wave with the conduction electrons. This research is concerned with an experimental and theoretical study of this interaction in metals and superconductors. The metals studied included cesium, magnesium, and niobium. A large part of the effort also includes the growth of high purity crystals and design of an ultrasonic system which automatically measures the attenuation in the presence of noise. (Author)
