Abstract
A recently given interstitialcy model for simple condensed matter states is tested by comparing predicitions of the model with available evidence for (1) the structure as given by the radial distribution function, (2) the dynamics of glasses found for the generalized vibrational density of states from inelastic neutron scattering measurements, and thermodynamic properties in the crystalline, glassy and liquid states given by (3) lattice parameter measurement determination of the thermal equilibrium concentration of interstitials in the crystalline stage, (4) the ratio of Young's modulus to volume changes during relaxation in the glassy state, and (5) the magnitude and temperature dependence of the specific heat in the liquid state. The structure, dynamics and thermodynamic properties are accounted for easily, simply and naturally in a quantitative, comprehensive and unified way by the interstitalcy model.
