On the basis of the experimental results obtained by using high-energy synchrotron X-ray diffration method, extended X-ray absorption fine structure spectroscopy and positron annihilation soectroscopy the atomic-sized model of radiation-structural changes for the glasses of As2S3-based system, As2Se3-based system and As2S3-As2Se3 system are established. In particular, it is established that for the ChVS of As-S sub-system in the frame of As2S3-As2Se3 pseudo-binary cut-section the nanoscale mechanism of radiation-structural changes is the same as one for the model binary As2S3 glass; due to the results of high-energy synchrotron X-ray diffration method, extended X-ray absorption fine structure spectroscopy and Doppler broadening of annihilation line this mechanism can be described by the Tanaka’s distortion model proposed for the explanation of photoinduced structural changes in the As2S3 glass.
