Calculation of thermophysical properties for crystals rare gases on elastic constants

For the crystals rare gases using the Van der Waals mechanism of interaction and data on the elastic constants have calculated the dispersion curves and the temperature dependence of heat capacity for Ar, Ne, Kr, Xe in compression. For the crystal rare gase Kr calculated dispersion curves at a pressure of 4 GPa and temperature dependence of heat capacity in the pressure range 0'8 GPa.
