The short-range order in vitreous Ge 1؊x Se x (2/34 4x4 41) at 80 K was studied by EXAFS spectroscopy at the Ge and Se K-edges. The results were analyzed using theoretical phase shift and amplitude functions and by comparison to crystalline GeSe 2 and Se as model compounds. The GeSe 4 tetrahedron is
main extends from GeS 2 to the composition with n ϭ 0.55 Glasses belonging to the Ga 2 S 3 -GeS 2 line are studied at room (n ϭ Ga/(Ga ϩ Ge)). The XAFS spectroscopy (X-ray temperature and at 7 K by XAFS spectroscopy at Ga and Ge absorption fine structure) is well suited to investigate sepa-K-edges.
