Bulk Modulus in Polycrystalline Inert Gas Solids at 0 K

Abstract

Bulk modulus values in the inert gas solids at 0 K are of interest because they may be compared with theoretical estimates based on assumed models of the solid. Various methods have been used to estimate the 0 K bulk modulus B(0) from experimental data. In this paper we propose a new method for estimating B(0) which is based on the empirical observation that saturated liquid phase sound velocities, when extrapolated linearly in density to 0 K solid density, give results agreeing with the best solid phase measurements.
