摘要：

We have used impulsive stimulated light scattering to measure the velocity of an acoustic wave propagating along the interface formed by a cobalt single crystal in contact with liquid helium to a pressure of 10 GPa. We have combined the measured velocities with x-ray diffraction data of cobalt under compression to obtain the elastic tensor elements c(44) and c(66), and with lower precision c(11), c(12), and c(13). We further show that using published inelastic x-ray scattering results for c(33) the associated uncertainties of c(11), c(12), and c(13) are substantially reduced.
