Abstract
The electron spin resonance spectrum of photo-induced paramagnetic centers in glassy As 43S 57 has been measured. From an analysis of the As 75 hyperfine tensor, we conclude that each of four different defect structures associated with neutral undercoordinated As atoms can account for the observed ESR spectrum. Arguments are presented to show that the diamagnetic structures of these centers are valence alternation defects. Two kinds of these valence alternation pairs require such large energy for creation that they can exist only when the glass becomes heterogeneous as a result of a strain-relief mechanism.
