Title: Ultrasonic attenuation studies in super-conducting lead
Author: Randorff, Jack Edward
Abstract: Measurements of the attenuation of 10 , 30 , 50 and 70 MHz longitudinal sound waves , propagated in the [100] , [110] and [111] directions , have been conducted on the normal and superconducting states of high purity unstrained lead . Analysis of the data has been presented in such a manner as to allow for the possibility of multiple superconducting energy gaps . Our data indicate the existence of a secondary gap . The data have also been compared to theoretical calculations for both weak and strong coupling models . Measurements of the ultrasonic attenuation have also been conducted on a sample of strained lead for the [100] direction . Preliminary statements have been made with respect to strain effects and a simple descriptive model has been proposed .
