摘要：

In situ X-ray diffraction at room temperature and under nonhydrostatic pressures up to 44 GPa confirms both the unusual equation of state of face-centered cubic (fcc) C-60 (fullerite), as well as its transformation to a new, as yet undetermined, crystalline structure. The phase transition begins at 19.5 (+/-5.0) GPa and is complete by 29.1 (+/-3.0) GPa on compression. The high-pressure polymorph is found to become amorphous upon decompression to pressures of 6 (+/-1) GPa.
