dc.description.abstract	Resonant Raman spectra of stoichiometric glass (g) g-As₄₀Se₆₀ have been investigated. It was observed that the increasing of excitation radiation energy hv>E₀ (E₀ is pseudogap width) changes a shape, intensity, and position of Raman peaks of g-As₄₀Se₆₀. The structure and vibration spectra of some As-Se clusters were calculated applying the ab initio method. In order to elucidate structural features of g-As₄₀Se₆₀, we combined the experimental Raman data and theoretical calculations.	uk_UA
