Study of tunneling impurities in alkali halides at low temperatures
… in the specific heat. For T > 0.6 K, the GrUneisen parameter, r, 3a/C, is isotropic and tt equal to +150±15 independent of temperature and lithium isotope. At lower temperatures, r becomes temperature dependent and anisotropic with respect to crystal orientation, probably because of …

Low-energy excitations in yttria-stabilized zirconia
… for glasses. This material also possesses a Gruneisen parameter larger than expected for a pure crystalline material with a magnitude similar to that observed in other crystals displaying glass-like low-temperature properties. Changing the Y203 content from 10.5 to 16 mole , increases the …

Thermoelastic and dynamical properties of perfluoroethane
… to measure temperature dependence of lattice parameter for the bcc solid and to characterize crystalline perfection. A measurement of longitudinal elastic wave velocity in the bcc phase was made, and a set of thermoelastic properties, including longitudinal and transverse velocities of sound, …

Lattice constant, thermal expansion, and isothermal compressibility measurements on argon single crystals
… the triple point of argon. The essential growth parameters were investigated and optimized so that single crystals of the necess,ary quality could be grown to a size as large as their container. From the measured compressibility and expansivi ty, valu'es of the thermodynamic properties of argon …

The velocity of sound in solid krypton
… fair. From. the:present bulk modulus values, the Gruneisen parameter of solid krypton was evaluated. From the longitudinal velocity in the nearly (110) direction and the polycrystalline velocities the second-order elastic constants were determined at 114 K. The difference c12 - c44 was also …

Application of [Lambda] to the fourth perturbation theory in calculating the equation of state of rare gas solids and fcc metals
… and the isothermal bulk modulus, and the Gruneisen parameter, for two of the rare gas solids, Xe and Kr, and for the fcc metals Cu, Ag, Au, Al, and Pb. The LennardJones and the Morse potential were each used to represent the atomic interactions for the rare gas solids, and only the Morse …

Surface acoustic wave techniques in laser pump-probe systems and its applications in studying mechanical properties of materials
… [SnSe][MoSe2]). I calculate the generalized mode Gruneisen parameter of Si in order to understand the relatively small attenuation of shear acoustic waves comparing with longitudinal acoustic wave in Si.
