Title: Temperature Measurements of Shock Compressed Liquid Deuterium up to 230 GPa

Abstract

Pyrometric measurements of single-shock-compressed liquid deuterium reveal that shock front temperatures T increase from 0.47 to 4.4eV as the pressure P increases from 31 to 230GPa. Where deuterium becomes both conducting and highly compressible, 30{<=}P{le}50 GPa , T is lower than most models predict and T<<T{sub Fermi} , proving that deuterium is a degenerate Fermi-liquid metal. At P>50 Gpa , where the optical reflectivity is saturated, there is an increase in the rate that T increases with P .
