Abstract

The high-frequency excitations of the molecular insulator C₆₀ are investigated theoretically. The model of a quantum well rolled into a sphere is used to calculate the dipole (multipole in the general case) modes of an individual C₆₀ cluster. If the spectrum and oscillator strengths of the collective modes of an individual cluster are known, the microscopic continuum approach can be used to calculate the spectrum of delocalized excitations in a cluster crystal. Then the ordinary dielectric constant formalism permits calculation of the optical characteristics of the material in the vacuum ultraviolet region studied.
