Title: Diffuse phase transition from the superionic to non-superionic state in Cu{sub 1.8}Se single crystal

The phase transition from the superionic to non-superionic state in a Cu{sub 1.8}Se single crystal is studied by neutron diffraction. In the superionic state, a diffuse halo related to the disordering of the cation subsystem is observed. It is established that the phase transition from the superionic to non-superionic state is the diffuse first-order phase transition occurring in the temperature range 250-180 K.
