Dear Nicolae,
Maybe ya ploho chitayu i ploho soobrazhayu, but even after your
explanation I can't see a way to calculate <R> from the results of
fitting described in chapters 6 & 7 of JAC 35 (2002) 338-346. From such
fitting you obtain only dispersion parameter c. Or I missed something?
Anyway, being "Rietvelders" we still have to deal with TCH-pV function
and we need to extract as much as possible correct information from it.
Hope we shall see more appropriate functions for microstructure
analysis in popular Rietveld programs.
Cheers,
Leonid
