Discussion of Solid C₆₀ Upon Lennard-Jones Potential

The properties of solid C₆₀ (fcc C₆₀) are discussed based upon Lennard-Jones potential U(R) = ε(σ/R)¹² - (σ/R)⁶. The magnitude of the constant ε is estimated by using the standard result of electrostatics for the interaction of two dipole moments of C₆₀ molecules. The cohesive energy and bulk modulus of the solid fullerenes are calculated by classical theory.
