Metallization of Fluid Molecular Hydrogen at 140 GPa (1.4 Mbar)
Abstract
Electrical resistivities were measured for liquid ${\mathrm{H}}_{2}$ and ${\mathrm{D}}_{2}$ 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/c${\mathrm{m}}^{3}$ 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.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
