Glasses from GexAs40−xS60, GexAs40−xSe60, GexSb40−xS60 and GexSb40−xSe60 families have been investigated by neutron diffraction. The well expressed “first sharp diffraction peak” of the neutron spectra at Q = 10–14 nm−1 has been explained by a pseudo-binary model of the structure of studied chalcoge...
