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

Figure 22

Differences (points) between EPSR fits (lines) to the average neutron (from Figure 5) and X-ray data (from [42], originally from [85])) for H2O data only (a) and D2O data only (b). The fits in this case include the oxygen isotope neutron difference data for each liquid [38] which for presentation purposes have been multiplied by a factor 20 for clarity. In both cases, the corresponding D2O (a) and H2O (b) difference data are shown for comparison, along with the simulated interference scattering for the same datasets.

(b) Fit to D₂O data
