I have a Programmable Divergence Slit (incident beam) in my difratctometer, that can work in automatic mode (irradiated length) or fixed mode (0.5 degree or 1.0 degree etc). What is the best collect mode for Rietveld Refinament??
I did refinement two difractograms collected in booth configuration (fixed 0.5 degree and automatic mode), the results in the fase "Periclase" (cement fase) changed, see below: Periclase with 0.5 degree = 6.08% Periclase wich automatic mode = 7.14% Note.: The refinement of the difractograms collected with automatic mode went converted to fixed mode by software. What do you think about this? regards =========================================== José Carlos Cordeiro Diretoria Técnica - Laboratório Central Centro Técnico - Curitiba Rodovia PR-092, 1303, Abranches, 82130-570 Curitiba-PR Votorantim Cimentos [EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]> www.votorantimcimentos.com.br Fone: + 55 041 3355-1380 Fax: + 55 041 3355-1358 ===========================================
