Figure 6. The real component of the form factor in Zn (Z = 30), represented by f₁ (e/atom). This is responsible for scattering, so that accurate computations of coherent and incoherent scattering, including Bragg-Laue or TDS extremes, should make use of this coefficient. This plot illustrates the effect of the wavefunction imprecision on the structure of Re(f). The "New Result" improves upon the qualitative structure given by Chantler [16] and by Henke et al. [32].
