Summary: The neutron diffraction measurement for superionic conducting glass (AgI)0.8 - (Ag2MoO4)0.2 was carried out at 10, 150 and 290K. The temperature dependence of structure factor S(Q) of (AgI)0.8 - (Ag2MoO4)0.2 has been discussed based on the theoretical treatment that includes thermal vibration of atoms in noncrystalline materials. The effective overall Debye-Waller temperature parameter B increases with the increase of temperature.
