Dear All:
I see that many people use the Rietveld method without a few minimal
knowledges of crystallography. It surprises that crystallography is not
given nowadays as a course in many university studies that treat with
solid crystalline materials. For which reason?
I think that the determination and/or the refinement of crystal
structures are not simply to use a Rietveld program. It is my personal
opinion.
Yours sincerely,
