摘要：

We have studied solid C60, measuring the shift of the optical absorption edge with pressure to 35 GPa. In the range of 0-17 GPa, extrapolation of the absorption edge indicates that metallization should occur by 33 GPa. However, from 17 to 25 GPa an irreversible transition to a "transparent phase" occurs. Raman scattering of the depressurized sample shows no trace of C60, diamond, or graphite, indicating that the transition involves the collapse of the C60 molecules into a new structure of carbon.
