Synthesis of UH7 and UH8 superhydrides: Additive-volume alloys of uranium and atomic metal hydrogen down to 35 GPa

UH7 and UH8 have been synthesized in a pure form by direct reaction of uranium with excess hydrogen in a laser-heating diamond anvil cell up to 96GPa. The sequence UH3, UH7, and UH8 is observed under increasing pressure using synchrotron x-ray diffraction. UH7 is stable above 35GPa and UH8 above 87G...
