説明
<jats:p>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 10GPa. We have combined the measured velocities with x-ray diffraction data of cobalt under compression to obtain the elastic tensor elements c44 and c66, and with lower precision c11, c12, and c13. We further show that using published inelastic x-ray scattering results for c33 the associated uncertainties of c11, c12, and c13 are substantially reduced.</jats:p>
