Electron scattering factors for charged Zn atoms. (a) The five-Gaussian (5G) parametrizations for neutral and +2 charged Zn atoms follow the red and green solid lines, respectively. The electron atomic scattering curves derived from International Tables for Crystallography Volume C (IT) for zinc and Zn2+ are shown by the blue and yellow dashed lines. The quasi-perfect fit illustrates the accuracy of the five-Gaussian parametrization in the 25–1 Å resolution range and the very low Rscat values (see Supplementary Table S4). (b) Atomic scattering factors for various charge states of zinc, as calculated from the linear combination of neutral and +2 charge states.
