Coherent diffractive imaging of individual nanoparticles, such as viruses, nanocrystals or clusters, has become feasible with the intense X-ray or extreme ultraviolet (XUV) light pulses free-electron lasers provide. Only recently, the development of powerful high harmonic generation sources delivering intense harmonics up to the XUV regime enabled laboratory-based imaging experiments. The scattering of multiple harmonics leads to multicolor diffraction patterns containing information on the nanoparticle shape. In an experiment at the Max-Born-Institute, Berlin, we studied the structure of large neon clusters. By comparing simulated scattering patterns with the experimental data we identified structures typical for rare gas cluster growth by coagulation. In addition when the neon clusters are produced from the liquid phase, scattering patterns indicating facet-like structures are observed.
