Abstract
The glass-transition, crystallization and melting in GexSel-x (0 $ x $ 0.33) have been studied by Raman scattering. Raman spectra exhibit some anomalous changes at the glass transition. On the basis of these anomalous features which relate to the structural changes, we investigate a medium range structure in glassy and liquid GexSel-x· In the Ge compo sition range of 0.04 < x < 0.18, both GeSe2 and Se crystals are much more difficult to be obtained than in the other Ge composition.
