Abstract
The sound velocity and attenuation of xenon near its critical point have been measured with a pulsed acoustic interferometer which incorporates phase-sensitive detection and signal averaging. Accurate data could be obtained over the frequency range from 0.4 to 7 MHz in spite of the very large attenuation. Results are given in detail along a near-critical isochore and are also reported along several isotherms.Keywords
