Abstract

The anticommutative Green’s functions and energy spectra of fullerene С28 and endohedral fullerene Zr@C28 with symmetry groups Td were obtained in the analytical form within the Hubbard model in the mean-field approximation. Group theory methods were used to categorize energy states and identify nonforbidden transitions in the energy spectra of С28 and Zr@C28 molecules with symmetry groups Td.
