Abstract
The sound velocity in xenon on the critical isochore was determined in Brillouin scattering measurements at scattering angles of 40° and 90°. The sound dispersion calculated from our data, ultrasonic data, and other Brillouin data agrees with the Kawasaki theory for a particular choice of parameters, but the dispersion in the Brillouin velocities is 2 to 3 times smaller than the theory predicts when values obtained for the parameters from other experiments are used.Keywords
