Hahaha! I just saw the question mark at the end of the first sentence. How am I supposed to know if they are short of articles?

Btw. I am intending to disappoint whoever "us" is referring to. Sorry...

I am not sure about treating their pattern as two independent structures despite being related through a group-subgroup relationship. Would need to check if there isn't a subgroup that explains all reflections.

Yes, I do have questions.

Is that the one opposite park bar?

Or to put it more profanely: I'd rather thank the engineer than the screwdriver for holding my wheels in place.

How would that be different from refining the crystallite fractions from Rietveld refinement? It's true, you get a volume fraction from that, which can be calculated into a mass fraction. Maybe Vaclav Petricek (Prague) of the Jana team might be a good address to speak to?

Actually, shouldn't the scattering probability be somehow proportional to the absorption cross section?

Let me think, I believe what you describe is being used somehow to reconstruct domains in metal samples. But I have not seen anyone using it for determining amorphous fractions.

Nope, Not in the way you do for SAXS. The trouble with single crystals is that (unless they are spheres), the beam path through the crystal has different lengths for each reflection, hence they are differently attenuated. Rarely a problem for organics, but massive for heavy absorbers.

I can see some defects in the pattern...

Und wenn der Engel Cosimo Anja Rützel Jr die Bücher Trashus und Realitus überreichen würde?

What would be an unreasonable request?
