Theoretical electron scattering intensities from negatively charged gold nanclusters containing 24 atoms, calculated for the structures shown at the top. Each of the curves is denoted by a symbol that corresponds to a particular structure. Shown at the bottom is the experimental scattering data (solid red line) together with the calculated one that fits it in the best way (dotted line) — that is, the tubular, capsule-like, structure marked G. The theoretically predicted best-fit structure is shown also on the right, with atoms in individual layer of the nanotube colored differently. The green strip accompanying the experimental data shows the experimental uncertainty.
