Phys. Rev. Lett. 76, 1860–1863 (1996)Metallization of Fluid Molecular Hydrogen at 140 GPa (1.4 Mbar)Received 28 August 1995; published in the issue dated 11 March 1996 Electrical resistivities were measured for liquid H2 and D2 shock compressed to pressures of 93–180 GPa (0.93–1.8 Mbar). Calculated densities and temperatures were in the range 0.28–0.36 mol/cm3 and 2200–4400 K. Resistivity decreases almost 4 orders of magnitude from 93 to 140 GPa and is essentially constant at a value typical of a liquid metal from 140 to 180 GPa. The data are interpreted in terms of a continuous transition from a semiconducting to metallic diatomic fluid at 140 GPa and 3000 K. © 1996 The American Physical Society URL:
