Abstract
During the past three years, ultrasonic techniques have been developed at Stanford University for efficient generation and detection of multi-gigahertz sound waves in liquid helium. This paper discusses two applications of these techniques: high resolution acoustic microscopy and direct measurement of low energy phonon dispersion. We begin with acoustic microscopy.
