Dear Junhua,

This does indeed sound like a description of a fiber diffraction
pattern. For example, as you probably already know, A-form DNA fibres
give large bands close to 3.4 Angstroms at the top and at the bottom of
the images. The exact positions of the bands are specific to the type
of fibre. I don't know what fibres diffract to 4.8 - 5.5 Angstroms.

I have never used MiTeGen mounting tools, so I can't comment on that.

>Another question about the MiTeGen mounting tools is that I always
observe a stong diffraction ring at about 5 A. Well, it is not exactly a
ring; it's actually two thick arches (pretty thick, roughly from 5.5 A
to 4.8 A), one at the top and the other at the bottom of the diffraction
patterns (nothing on the left-hand or right-hand side). Does anybody
have any idea what this might be (fiber?)?
