Abstract
The temperature dependence of the mean-square thermal tensor of KH2AsO4 in the paraelectric phase has been investigated by neutron diffraction structure analysis. All the tensor elements except u22(H) are extrapolated to zero and u22(H) gives a positive intercept at 0K. The temperature dependence of the H-site separation, δ, was obtained and was compared with that of KH2PO4. The result is well described by the order-disorder behavior of hydrogen.
