Phase diagram determination of $\alpha$-Uranium under pressure by single crystal x-ray diffraction

ORAL

Abstract

We grew single crystal $\alpha$-Uranium and studied its crystallographic properties at pressures up to 1.3 GPa using the ID-27 beam-line at the European Synchronon Radiation Facility. At low temperatures and pressures, we observed clear satellite peaks on the orthorhombic $\alpha$ structure, indicating one or more transitions into the charge-modulated phases.
