Stretching density of states od Deuterium Sites in polycrystalline D2O

Abstract

For the first time inelastic neutron scattering measurements on a poly-crystalline sample of D2O up to the O-D stretching region are presented. The data have been analysed, treating the coherent scattering contribution within the incoherent approximation. The O-D density of states for the deuterium sites has been extracted and compared with the available Raman and neutron spectra of ice Ih
