      abstract     = {(As(0.4)S(0.6))(100-x)Ag(x) glasses (x = 0, 4, 8,
                      $12 at.\%)$ have been studied with high-energy x-ray
                      diffraction, neutron diffraction and extended x-ray
                      absorption spectroscopy at As and Ag K-edges. The
                      experimental data were modelled simultaneously with the
                      reverse Monte Carlo simulation method. Analysis of the
                      partial pair correlation functions and coordination numbers
                      extracted from the model atomic configurations revealed that
                      silver preferentially bonds to sulfur in the As(2)S(3)-Ag
                      ternary glasses, which results in the formation of
                      homoatomic As-As bonds. Upon the addition of Ag, a small
                      proportion of Ag-As bonds (N(AgAs)≈0.3) are formed in all
                      three ternary compositions, while the direct Ag-Ag bonds
                      (N(AgAg)≈ 0.4) appear only in the glass with the highest
                      Ag content $(12 at.\%).$ Similar to the g- As(2)S(3)
                      binary, the mean coordination number of arsenic is close to
                      three, and that of sulfur is close to two, in the
                      As(2)S(3)-Ag ternary glasses. The first sharp diffraction
                      peak on the total structure factors of As(2)S(3) binary and
                      (As(0.4)S(0.6))(100-x)Ag(x) ternary glasses is related to
                      the As-As and As-S correlations.},
