The Radial Distribution Functions of Water as Derived from Radiation Total Scattering Experiments: Is There Anything We Can Say for Sure?

Table 1

List of neutron total scattering experiments on mixtures of heavy and light water as run on the SANDALS and NIMROD diffractometers at ISIS over the period 2001–2012. Also shown are the neutron weights outside each site-site term in the total scattering cross section.
