Spectroscopic methods such as Raman scattering and IR absorption, as well as structural methods such as x-ray and n-diffraction, offer rather ambiguous interpretation of the high-frequency phonon spectrum of CsH 2 PO 4 (CDP), especially regarding the

The strong anisotropy of the proton mean kinetic energy, Ke(H), in a single crystal of KH2PO4 (KDP), measured by deep inelastic neutron scattering (DINS), is compared with that calculated for its Cs analogue, CsH2PO4 (CDP) in the ferroelectric (FE) a
