Hi, Researchers,
Recently, I am learning a tutorial of the Rietveld refinement online. It says that the structure factor of P42/mnm TiO2 can be expressed as the plot1 shows, the A factor.
I want to know, in which references I can search the structure factor expressions for other space groups, such as R-3m. I mailed the author and am told that They are all listed in the old international tables vol a (red cover version). But, I can not find it as it is too old.
Cuould someone recommend some other references for that ?
