摘要
The phenomenon of unusual light scattering observed earlier during exposure of the bulk glasses As2S3 and GeS2 to polarized light with hupsilon < E(g) which causes- optical anisotropy and gyrotropy in the samples is considered here as the structural diffraction. For the first time the formation of gigantic non-crystalline clusters (GNC) of the micrometer size and gigantic lattices due to the GNC regular packing is established. It is shown that the existence of a dynamic subsystem consisting of soft atomic configurations in the form of three-centre bonds (TCB) in addition to the basic subsystem of rigid covalent bonds is a necessary condition for the creation of GNC which have collective TCB on their mobile boundaries.
