The proton dynamics of water at 273.4\ifmmode^\circ\else\textdegree\fi{}K and ice at 268.7\ifmmode^\circ\else\textdegree\fi{}K have been studied by scattering of cold neutrons. It is shown that the sharp peaks in the ice spectrum are flattened out on melting and that the spectra from ice and water are thus significantly different. The main features of the spectra are rather independent of the scattering angle, and it is therefore concluded that multiphonon scattering cannot explain the divergency of earlier results on water close to the freezing point.
