The crystal structure and defect structures of C6o material have been studied by means of X-ray diffraction, high-resolution electron microscopy and electron diffraction. The diffraction measurements show that the C60 crystal has the face-centered cubic (fcc) structure with lattice parameter a = 1.4
## Abstract Highβpressure Raman spectra of fullerite, a solid form of C~60~, were measured at pressures up to 4 GPa and room temperature. A change of slope (d__v__/d__P__) of the frequencyβpressure plots for the __A__~g~ pentagonal pinch mode and the __A__~g~ breathing mode was observed at 1.3 GPa,
Vibrational Raman studies on Cse up to 18.0 GPa and between 4 and 360 K are presented. No significant changes are observed up to IO GPa; mode-Grthteisen parameters are calculated. The low pressure, temperature-dependent Raman spectrum shows a sharp shift in peak position and width at 240 K. This is
