Abstract: The most abundant fullerene molecule, C60, has just the right size, chemical stability and activity to host a large variety of atoms. Endohedrally doped fullerenes have been synthesised in the past. A rare earth doped fullerene shows an icosahedral symmetry. A group theoretic treatment of f-electrons in a strong icosahedral crystal field has been discussed in the present study. This method shows a convenience over the conventional structures given by Racah for the treatment of f electrons in strong crystal fields. It is expected that it will make the perturbation calculations easier. These calculations will lead to an understanding of magnetic properties of nano devices.
