Abstract
- A model of uranium hexafluoride is suggested that is based on the empirical pair potentials of U-U, F-F, U-F used for both intra- and intermolecular interactions. The potentials for this model are obtained from the lattice parameters and the thermal expansion coefficient of UF6 crystal using the molecular dynamics simulation under the periodic boundary conditions with constant volume and temperature. Within the framework of the model, the thermal expansion and sublimation of crystalline UF6 are investigated. A set of potential parameters is identified that provides satisfactory simulation of both UF6 crystal and the dependence of the UF6 saturated vapor pressure on temperature. [ABSTRACT FROM AUTHOR]
