Energies of higher multipole vibrations of fullerenes in a semiclassical approach

Authors


Abstract

Starting with a brief description of the local current approximation (LCA) as previously applied to the photoionization cross section of C60, we discuss the results of higher multipole resonances of fullerene molecules. The comparison to data obtained from electron scattering experiments reveals the adequacy of the semiclassical approach as well as the collective nature of even high L resonances. Similar to the results of the dipole case, the coupling of surface and volume plasmons mode in C60 molecules is seen to shift the peaks slightly toward lower energies. © 2011 Wiley Periodicals, Inc.
