Analytical formula to estimate the van der Waals interlayer interaction coefficients for nested spherical fullerenes

Analytical formula to determine van der Waals (vdW) interlayer coefficients of nested spherical fullerenes is suggested. The continuum approximation together with the Lennard-Jones potential is utilized. It is shown herein that the greatest contribution to the vdW interaction comes from the adjacent layers and the contribution from a remote layer may be neglected. The vdW interaction is found to be strongly dependent on the radius of the layer, especially when the radius is small enough (<6 nm).
