Rietveld Workshop

v\:* {behavior:url (#default#vml);} Dear Colleagues, It's a great pleasure to announce the second Tunisian powder diffraction workshop entitled : " Advanced Methods in Rietveld Refinement " It will be held in the Engineering School of Nabeul (Tunisia) 27-28-29 march 2017.

Re: Stoichiometry and occupancy fractions of solid solutions

To increase sensitivity to partial/mixed occupation and also solve the case of 3 or more atoms in the same site (you have an infinite number of solutions that give you the same scattering factor, both x-ray and neutrons) we are developing a combined XRD-XRF analysis. Some preliminary

If you have multiple atoms/vacancies on the same site, it is also worth considering what resonant scattering can do for you. Zhang, Y.; Wilkinson, A. P.; Lee, P. L.; Shastri, S. D.; Shu, D.; Chung, D. Y.; Kanatzidis, M. G., Determining metal ion distributions using resonant scattering at very
