On the possibility to consider fullerene shell C60 as a conducting   sphere
  Correctness of the model representing the fullerene shell C60 as a conducting sphere has been analyzed. The static and dynamical polarizabilities of the molecule C60 have been calculated on the basis of experimental data on the photo-absorption cross- section of fullerene. It has been shown that the real C60 in the static electric field behaves most likely as a set of separate carbon atoms rather than as a conducting sphere and its static polarizability exceeds by more than two times that of conducting sphere.
