Application of icosahedral symmetry to the study of electronic and optical properties of C60 fullerene
We report on the symmetry aspects of our quantum-mechanical study of static t1u ÄHg Jahn-Teller problem in C60 anions and low energy monoexcitation spectra of C60 fullerene. The symmetry adapted configuration interaction method is used to define the multi-electronic wave functions and to reduce the complicated calculations of the matrix elements. The role of electron correlation effects in the modeling of fullerene properties and appropriate shape of electron-electron interaction potential are discussed.
