In this work, structural properties and phase equilibrium of C-60-C-70 soli
d solutions are studied, These properties are investigated on the basis of
the Lennard-Jones potential in the high-temperature limit where pure phases
of C-60 and C-70 are orientationally disordered and exhibit fee lattices.
The results agree well with the available experimental and theoretical work
