Results obtained by the method of isotopic substitution in neutron diffraction
on the structural ordering in the glassy semiconductor 
show that the short-range order of the network former 
is retained
and the Ag-Ag intermediate-range order is similar to that of the crystalline
network modifier (
). By comparison with results for the glassy fast-ion conductor
it is concluded that silver nearest-neighbour interactions are
responsible for the absence of cationic motion.
