Figure 4. Diffraction data for trapped C60+ ions. (a) The average diffraction intensity Isig vs s (-1), is obtained by averaging CCD pixels forming a circle around the e-beam axis. (b) Comparison of the experimental (solid curve) and theoretical (dashed curve) molecular scattering intensity Imol. (c) The difference delta-Imol is shown with the uncertainty of +/-1sigma (gray band) displayed at each data point.
