Dear Kurt, It seems that the problem is in wrong sample-to-detector distance which results in the nearly linear angular dependence of the peak displacement. Regards, Leonid * Leonid A. Solovyov Institute of Chemistry and Chemical Technol

Dear Rietvelders, (I hope this list is appropriate for this question). I am trying to set up a new D8 diffractometer from Bruker, and have it set up with a Vario monochromator focusing on a sample in a capillary. Of course I hope to do Rietveld refinement on the samples eventually. But there
