I'm analysing the crystallite size of a ball milled powder, and am not sure about my calculation method using topas.
when I do the calculation using topas, if I don't consider the strain factor, only choose a L or G profile which gives a smaller error value, and look at the lvob value for crystallite size, then the crystallite size is 5.8nm.
but when I start to add in the strain factor, for both strain_L and strain_G, the error value is always larger than the value itself, same goes for e0. so in this case, is the strain still needs to be considered? how should I select from strain_L and strain_G?
the crystal size itself does not differ much no matter I add in strain or not, but still I'm wondering how to consider this factor during refinement
Thanks!
