Phys. Rev. Lett. 86, 4568–4571 (2001)High-Pressure Elastic Properties of Solid Argon to 70 GPaReceived 6 December 2000; published in the issue dated 14 May 2001 The acoustic velocities, adiabatic elastic constants, bulk modulus, elastic anisotropy, Cauchy violation, and density in an ideal solid argon (Ar) have been determined at high pressures up to 70 GPa in a diamond anvil cell by making new approaches of Brillouin spectroscopy. These results place the first complete study for elastic properties of dense Ar and provide an improved basis for making the theoretical calculations of rare-gas solids over a wide range of compression. © 2001 The American Physical Society URL:
