Dear all, what is he right factor in case of a laboratory diffractometer with " sealed tube or rotating anode source" and especially for a goebel mirror?

If your radiation comes from a sealed tube or rotating anode source without monochromator there is no polarization of light and the factor is 0.5, the use of a filter does not change the polarization state. If you have an incident beam monochromator it depends on the material of the monochromator (or better on the diffraction angle). If you are using synchrotron radiation you will need something in the range 0.95 to 1 depending on the optics of the beamline. I hope this helps, Leo 2015-06-03 5:56 GMT-03:00 Davide Levy <davide.lev...@gmail.com<mailto:davide.lev...@gmail.com>>: Hi to everybody, Which polarization correction is better to use in GSAS for data collected with a linear detector without monochromator? thanks Davide ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Please do NOT attach files to the whole list <alan.he...@neutronoptics.com<mailto:alan.he...@neutronoptics.com>> Send commands to <lists...@ill.fr<mailto:lists...@ill.fr>> eg: HELP as the subject with no body text The Rietveld_L list archive is on http://www.mail-archive.com/rietveld_l@ill.fr/ ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ -- Dr. Leopoldo Suescun Prof. Agr (Assoc.
