Abstract / Description of output

In situ high-pressure high-temperature x-ray diffraction and optical studies have been conducted on solid oxygen between 10 and 20 GPa and up to 700 K. Optical observations and Raman spectroscopic studies have been utilized to confirm the existence of eta-O-2 and to identify phase behavior and phase boundaries of beta-, epsilon- and eta-O-2 at elevated temperatures. Subsequent single-crystal synchrotron x-ray diffraction studies yielded the structure of the eta-O-2 phase at 15.9 GPa and 625 K. (C) 2009 American Institute of Physics. [DOI: 10.1063/1.3118970]
