Explaining for broadening of peaks due to a shift of theta in theta-two theta scanning?

a theta-2theta scan with theta shifted ? By the way, do you know others ways, besides the razing incidence, to avoid the dominant peaks of substrate over the thin film ? Thanks a lot in advance for your any helps. Best regards, --- Huy LE-QUOC, Doctorant LPSC/UJF-Grenoble INP-CNRS, Centre d

What is a good sequence for refinement of (U,V,W) of a multiphase sample ?

phases? Or should we refine simultaneously W for all phases and then V and U for all phases? Do anyone of you have any experience on this case ? Thank you in advance for your kindly helps. Best regards, --- Huy LE-QUOC, Doctorant LPSC/CNRS - Centre de Recherche Plasmas

How to calculate "Occupation number" in FullProf

the Occupation number be "/normalised to the multiplicity of the general position of the group/" ? I have tried to calculate for Mg2Sn (Fm3m), with Mg at the site 8c and Sn at 4a, then Occupation number of Mg is 8/192 and that of Sn is 4/192. Is this right ? Thanks in advance for your any h
