Phys. Rev. Lett. 48, 97–100 (1982)Low-Temperature Equation of State of Molecular Hydrogen and Deuterium to 0.37 Mbar: Implications for Metallic HydrogenReceived 6 July 1981; published in the issue dated 11 January 1982 The T=5 K isotherms of molecular H2 and D2 as well as the index of refraction to 370 kbar have been measured with a diamond-anvil cell. The hydrogens are somewhat softer than predicted from extrapolation of low-pressure measurements and the transition to the metallic atomic state is predicted to fall between 1.9 and 5.6 Mbar. © 1982 The American Physical Society URL:
