Abstract
We have observed the second-sound contribution to the Brillouin spectrum of liquid near the transition at saturated vapor pressure and at 25.1 atm. Its spectral shape is compared with theoretical predictions. We have determined the intensity ratio of second- and first-sound scattering between , and we present data on the dispersion and damping of high-frequency first and second sound.
