Abstract
The integral spectra of the dielectric permeability of corundum within the region 8–40 eV in the polarizations E ⊥ C and E ∥ C are decomposed into 18 Lorentz elementary oscillators. Their principal parameters, namely, the energy E i , half‐width H i , band area S i , and height of the maximum ε2max, are calculated and the main features are established. An analysis of the well‐known results obtained by two models of the reproduction of the ε2 spectra with the aid of a large number of fitting parameters and theoretical calculations of the corundum bands is carried out.
