Abstract
The anticommutative Green’s functions and the energy spectrum of fullerene C60 have been calculated using the Hubbard model in the mean-field approximation. Based on the obtained energy spectrum, the interpretation of the experimentally observed bands of optical absorption has been proposed and the parameters of this fullerene, by which it is characterized in the Hubbard model have been calculated. The results agree fairly well with the experimental data.
