Abstract: | A complete set of fundamental optical functions of fullerite (C60) films in energy ranges of 2.5–5.0 and 4.0–9.0 eV is calculated using the known spectra of the imaginary and real parts of
the dielectric constant. An integrated spectrum of the dielectric constant is decomposed into elementary components. Three
basic parameters of each component (the maximum and halfwidth energies and oscillator strength) are determined. Based on the
known theoretical calculations of fullerite zones, a scheme of the nature of these components of the dielectric constant is
suggested.
