Zitat von George DeTitta <deti...@hwi.buffalo.edu>:
I'd appreciate it if people could tell me their experiences with what I would call "phantom crystals", or "ghost crystals". These are objects that display the seeming morphology of crystals (clear facets, sharp edges)
... There is also a second type of "ghost crystals", those which do not have edges at all, with a ball- or egg-like apearance and which diffract perfectly well!
but do not diffract X-rays AT ALL. I would not count objects
that diffract to 30 A in this category. I mean objects that don't show a single Bragg spot. George T.
