Abstract
An anion C-60 pseudopotential is determined from an ab-initio-based approach. First, ab-initio calculations are performed to calculate the electronic charge density and the total electrostatic potential. Second, the effective dependence of the pseudopotential on the radial degree of freedom is extracted from the angular average of the total electrostatic potential. Finally, the resulting effective pseudopotential is fitted to a simple analytical form which can be applied in further dynamical simulations of fullerene-based compounds.
