heal.abstract	We have measured the Raman scattering spectra of β-GeSe2 single crystal (high temperature modification with layered crystal structure) under hydrostatic pressures up to 8 GPa at room temperature. According to Raman spettia, die pressure increase produces firstly transformation from layered crystal structure bio fully disordered structure (at 6.2 GPa). Further increase of the pressure up to 7.2 GPa yields strong indication of a phase transition from the disordered phase to the α-GeSe2 (low-temperature modification of GeSe2 with three dimensional crystal structure). At 8 GPa, this modification transforms back to the disordered phase. All these phase transformations are reversible.	en
