Abstract:
The spectra of sets of optical fundamental functions are determined for an indium-bromide crystal in the range of 0–30 eV at 4.2 K for the polarizations $\mathbf{E}\parallel \mathbf{a}$ and $\mathbf{E}\parallel \mathbf{c}$. The calculations are carried out using experimental reflection spectra $R(E)$ and several software packages. Their basic features are established.
