Diffraction, amorphous substances order

An ingenious approach to the autoionization process was suggested by Tomelini and Fanfoni [32]. They examined diffraction processes in the framework of autoionization, i.e., a second-order process. More exactly, they studied only the second stage of autoionization, namely, the secondary electron emission from the intermediate state where the core hole is coherently distributed over the crystal. With such an approach it was shown that in crystals this diffraction contribution enhances fine structure as compared to the amorphous substance. However, the applicability of such a model is determined by the probability of the occurrence of the core hole distributed coherently over the crystal. More conventional... [Pg.196]

The capabilities of Oberlin and Bonnamy to see the big picture, and thus synthesize the advancements in seemingly unrelated carbon research fields, both old and new, have been amply demonstrated in previous volumes of this series. Here they bring order to the often confusing issue of disordered carbons, whose relevance has increased tremendously as a consequence of the often frustrated (and certainly incomplete) conversion of a wide variety of carbon precursors to nanotubes, fullerenes, or graphene. As they reviewed all the relevant information, unexpected new concepts emerged related to the carbonization and graphitization processes, and they were able to define more precisely the domain of existence of the various substances such as amorphous carbon and [basic structural units], as well as [local molecular orientations and] turbostratic carbons. .. by using diffraction techniques or their associations. ... [Pg.277]
