Band structure and optical properties of gallium

This is the authors' abstract. We don't add key points for this paper.

The optical properties of clean, evaporated films of gallium have been studied at several temperatures. The observed spectra were interpreted on the basis of a pseudopotential calculation of the band structure. The position of characteristic peaks in the spectra agreed well with the predictions from the optimized model potential for gallium recently published by Appapillai and Williams (1973). The shift of the peaks with temperature was too large to be accounted for by shifts in the atomic form factor alone; the Debye-Waller factor must be included to explain the observations.
