摘要
Elastic and inelastic scattering of neutrons is measured in KH2PO4 single crystals as a function of the orientation of hydrogen bonds relative to the momentum transfer. The results show that at room temperature the protons tunnel between two equilibrium sites. The distance of the two sites, their orientation relative to the c-axis and an asymmetry parameter are determined. © 1969.
