Ultrasonic Attenuation in Antimony. I. Geometric Resonance

Abstract

Geometric resonances in ultrasonic attenuation were observed in antimony. The experimental method used was the continuous method. The sound frequency used was primarily 60 Mc/sec, with some observations at 132 and 252 Mc/sec and magnetic fields 4-200 G. For $q\parallel z$, Shoenberg's carriers were observed and ${\alpha }_{11}$ determined. For $q\parallel x$ and $q\parallel y$ other highly anisotropic carriers were observed.
