Abstract

The phases of cerium above 5 GPa have been studied using angle-dispersive powder diffraction techniques. The phase obtained between 5 and 12 GPa at room temperature with filings of Ce has a monoclinic, distorted-fcc structure with four atoms in a C-face-centered unit cell. Heating to 373 K for many hours yields the known alpha-U phase. With a single cut piece as a sample, the alpha-U phase is obtained at room temperature.
