Abstract
Using non-resonant, broadband transducers fabricated from PVDF films, frequency sweeps have been performed in He-3-B from nominally 10 to 60 MHz at nearly constant temperatures below 250 mu K at about 1 bar. By studying the changes in the group velocity and attenuation as a funct ion of frequency, the real squashing(J = 2+) mode has been identified in the T --> 0 limit.
