X-ray study of pressure-collapsed fullerite. Physical Review B 48(11): 8474-8475.1098-0121http://nrs.harvard.edu/urn-3:HUL.InstRepos:10357543X-ray-diffraction studies are described for a new phase of carbon called collapsed fullerite (CF) that was produced by application of high pressure to fullerite (C\(_{60}\)). At \(\sim\)20 GPa there is an irreversible transition to a phase that has neither the (111) Bragg peak of diamond nor any of the Bragg peaks associated with the fcc phase of C\(_{60}\). The spectrum of CF is flat and featureless in the range of study.en-USJournal Article2013-03-0110.1103/PhysRevB.48.8474
