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

Figure 11

Poisson functions in 𝑟 space (a) and 𝑄 space (b) for several orders up to 𝑛=25 using a width parameter 𝜎=0.2 Å. Note how in 𝑄 space the increasing orders sample more and more of the small 𝑄 part of the scattering data.

(a)  𝜎=0.2 Å

(b) 𝜎=0.2 Å
