(a), (b) TOF scattered and transmitted spectra from a 1 mm H2O sample at 298 K measured with incident-beam wavelengths of λi = 5 Å (a) and 7 Å (b) at LD = 1.6 m. (c), (d) TOF scattered spectra from D2O samples at 298 K measured with an incident-beam wavelength of λi = 7 Å for samples with different thicknesses with a beam size of 5 × 5 mm (c), or for a sample thickness of ts = 2 mm with different beam sizes (d). The meaning of different line types and colours is discussed within the main text. The vertical arrows in (a) and (b) indicate the elastic part of the spectrum used in the data analysis. |
