ABSTRACT
The C60-samples after high pressure treatment up to 13 GPa and high temperature treatment up to 1300K have been studied by TEM-methods. The thermobaric treatment of C60 has resulted in the appearance of new crystalline states with fcc- and distorted fcc-lattices. Besides, an unusual structure has been found. Diffraction patterns of this structure contain arc-reflections, as well as disordered carbon structure, but with a regular arrangement in reciprocal space. All the structures observed can be explained by moving of molecules closer together and by bonding of molecules.
