Multipole Excitation of C₆₀ Molecules in a Semi-Classical Approach

This work investigated the collective dynamic response of the 240 delocalized valence electrons of the C₆₀ molecules to external stimulations such as electromagnetic radiation or scattering of the charged particle, using local current approximation (LCA), which is a semiclassical approach based on general variational principle. Here the bulk of the valence electrons is treated as a semi-classical fluid that exhibits both the translational and compressional vibrations. The coupling of these two modes has been studied and the results are in good agreement with the experimental data from photoionization experiments on C₆₀.The same semi-classical approach has been applied to study the energies of higher angular momentum resonance.
