====Girifalco potential====
The Girifalco [[intermolecular pair potential]]  is given by <ref>[http://dx.doi.org/10.1021/j100181a061 L. A. Girifalco "Molecular properties of fullerene in the gas and solid phases", Journal of Physical Chemistry '''96''' pp. 858-861 (1992)]</ref> (Eq. 4):

:<math>\Phi (r) = -\alpha \left[ \frac{1}{s(s-1)^3}+ \frac{1}{s(s+1)^3}- \frac{2}{s^4}\right] + \beta \left[ \frac{1}{s(s-1)^9}+ \frac{1}{s(s+1)^9}- \frac{2}{s^{10}}\right]</math>

where 

:<math>s=\frac{r}{2a}</math>

:<math>\alpha = \frac{N^2A}{12(2a)^6}</math>

:<math>\beta = \frac{N^2B}{90(2a)^{12}}</math>

where <math>N</math> is the number of atoms on each sphere, i.e. N=60.
