To see what individual bowtie crystal pairs associated with icosahedrally twinned fcc crystals look
like in a darkfield decomposition array, consider first this 32x32 array of darkfield images from a 20-crystal Pd nano-particle
formed by solid state reduction of Pd salts in a polymer matrix, as viewed down one of it's
10-fold symmetry axes...

Although this set of darkfield amplitude images (with the brightfield image in the center) does not separately represent all of the diffraction spots in the 10-fold symmetric image power spectrum, it does this for quite a few of them. The small angle "bowties" represent crystal pairs associated with Pd (200) and (220) lattice spacings (1.945 and 1.375 A in size), while the large angle bowties (or "butterflies") represent Pd (111) spacings (2.246 A in size) shared by pairs of bowties interfaced along a common boundary.
With this information in hand, now consider the 32x32 darkfield array from a large randomly-oriented metal cluster provided by Max Bertino at UM-Rolla. At least one well-defined bowtie resides therein, whose lattice indexing we are currently in the process of investigating for consistency with the icosahedral model above. Can you find it?
