摘要：

We have examined the nucleation of C60 clusters via molecular-dynamics simulations. We find that it is possible to nucleate a "buckminsterfullerenelike" cluster with no symmetry-, or volume-imposed constraints from a "hot plasma" of carbon atoms. The growth sequence for buckminsterfullerene is dominated by the nucleation of long carbon chains in the initial phase. As the nucleation process proceeds, these chains branch and form polycyclic rings. We find an abrupt onset of ring formation at a temperature which corresponds to the melting point of graphite.
