The object that approaches the most a ghost to my mind is a picture of
a bubble trapped into a lipidic cubic phase of the detergent
beta-octyl-glucoside, it can be found in the article from P. Sakya,
J.M. Seddon & R. Templer (1994) J.Phys II France 4:1311. I got also
crystals of membrane protein (i.e. not bubble) in the same detergent
that exhibited the same faceted cubic habits, they often disappeared
quickly (a few days) and were to soft to be manipulated.

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) 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.
