Figure 2. Diffraction data for a neutral C60 beam. (a) The average diffraction intensity Isig vs s (Å-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 in with the uncertainty of +/-1sigma (gray band) displayed at each data point.
