Pressure-induced structural phase transitions in solid xenon
Abstract
Pressure-induced structural phase transitions have been observed in solid xenon by high-pressure x-ray diffraction methods up to 137 GPa (1.37 Mbar). The face-centered-cubic structure is unstable above 14 GPa and transforms to an intermediate, close-packed phase. Above 75 GPa a further transition takes place to the hexagonal-close-packed structure which remains stable to at least 137 GPa. At this pressure, where V=10.5+/-0.2 cm3/mol (V/V01=0.30), there is no evidence for band-gap closure.
