Hi All: I just posted some problems on the tutorial of the refinement of sodium-para-hydroxybenoate. For this materials, the anisotropic broadening is mainly...
... The peak broadening increases with diffraction angle as 1/cos(Theta) in the case size effect and as tan(Theta) in the case of strain. This is valid for...

Dear Anoop, you probably have to start from a good book on diffraction (Cullity or similar) and read carefully the texture (or preferred orientation part) plus...
Dear Yee Yan, I don't know Dr Robert's tutorial, but evidently he is refining things that you don't if he has 39 variables and you have only 11. If you are in...
