Distorted f.c.c. arrangement of gold nanoclusters: a model of spherical particles with microstrains and stacking faults

A model of distorted f.c.c. arrangement for silica-supported gold nanoclusters brings about satisfactory fitting to X-ray diffraction data and is confirmed by EXAFS analysis. Using ordered f.c.c. and noncrystalline (icosahedral and decahedral) components, the X-ray diffraction fitting is also good, but the results are in contrast to EXAFS data.
