Figure 2
Experimental neutron total scattering functions from BaTiO3 at 15 K (Senn et al., 2016BB13), using ρ0 = 0.0779 atoms Å−3, determined from Rietveld refinement of the data. The various functions are defined using the equations given in Table 1[link]. The asymptotes at high and low Q (or r, as appropriate) are highlighted using red dashed lines with values for reciprocal-space functions from Table 4[link]; all real-space function limits are clearly seen to be 0 or 1 except for the low-r limit of GK(r), which is −〈bcoh2 = −0.145 barn.
