摘要
Cesium hydrogen sulphate is one of the most extensively studied superprotonic conductors with hydrogen bonds. The first-order phase transition, from the low-conductivity to high conductivity phase takes place at 414 K. The crystallographic structure of both phases has been established using high-resolution powder diffraction. Quasi-elastic neutron scattering gave information about the spatial and temporal characteristics of proton transport. The present paper reports the results of reverse Monte Carlo modelling of diffraction data which makes it possible to obtain the diffusion pathways for protons. (C) 1998 Elsevier Science B.V.
