Phase diagram of C-60 from ab initio intermolecular potential

Recently a new intermolecular potential for C-60 was derived from ab initio calculations. Using this new interaction potential we numerically study th e phase diagram of fullerite. Several numerical techniques are used in orde r to ascertain the correctness of the results. We predict that C-60 can be found in the liquid state for densities between 0.468 and 0.845 nm(-3) and temperatures between 1881 and 2012 K. (C) 2000 American Institute of Physic s.
