Dear All, Hope my e-mail finds you well.
I am a beginner in Rietveld Analysis and I am working on structure refinement of my powder diffraction data. For structure refinement of my XRD data ( taken from pure ZnO powder) what I realized is, I should perform a Pawley refinement. It actually gives me some refined lattice parameters that I have to use them in the next step i.e refining the atomic positions. Therefore, I am under the assumption that once I performe a pawley refinement, then I have to save it as an input file to use in the lunch mode. right? One of my basic questions ( sorry if it is too basic) is that when I want to start refining the atomic positions, should I already create the rigid body myself in the editor section of the TOPAS? or it will be created by its own when I use my Pawley refinement results in the lunch mode? If I need to create the rigid body myself, then how can I make the created rigid body to be refined when I start the refinement in TOPAS? I was wondering if any of you could explain how to take the last step i.e refining the general atomic positions using my previous pawley refinement results. Thanks in advance, Sirous. -- *Sirous Khabbaz Abkenar* *Ph.D. Student, Materials Science & Engineering,* *Faculty of Engineering and Natural Sciences,* *Sabanci University,* *Tuzla, Istanbul, 34956 Turkey* *khabbazabke...@sabanciuniv.edu <khabbazabke...@sabanciuniv.edu>* *Tell: +90 507 094 7291 <%2B90%20507%20094%207291>*
