Abstract
The high compressibilities recorded in experiments on liquid-deuterium compression and the significant scatter of experimentally measured densities in the region of anomalous compressibilities are explained by the manifestations of an unusual dielectric-metal phase transition: from a dense molecular gas to a liquid-metal atomic gas. This transition has previously been described by us and called the dissociative phase transition (DPT). The dissociative equilibrium curves, the isotherms, the DPT binodal, and the Hugoniot adiabat have been calculated. The DPT has been shown to be a transition of a new, non-van der Waals type.
