WebbA possible proton collective motion in ferroelectric KH2PO4 is studied on the basis of the tunneling model by making use of the statistical mechanics of irreversible processes. The spectrum and the damping constant of this motion are calculated, including their temperature dependence.

WebbOur measurements indicate a sharp phase transition preceding the increase in the vapour pressure of water. We carefully checked the loss of weight of KH2PO4 and KD2PO4 crys- tals that had just crossed the transition point and found it to be less than 0. 15 per cent, indicating almost no escaping of water outside of the crystal.
