Abstract
Jointly analyzing the absorption spectra and the interference patterns in the transmission spectra of GaSe at pressures between 1 and 5530 bar, further evidence is given relating to polytypic transformations in GaSe, namely: the intrapolytypic transformation when the pressure is increased from 2790 to 3350 bar and the interpolytypic transformation when the pressure is increased from 4340 to 4710 bar. This interpretation is confirmed by the analysis of the pressure dependence of the energy position of the exciton line. The possible mechanism of these transformations is discussed. Taking account of the intrapolytypic transformation, the pressure influence on the low-energy tail of the exciton lines is considered. [Russian text ignored]
