Apu,
I would try bimodal distribution of crystallite sizes: in fullprof you can use
two phases with the same structure and different peak shape and broadening.

Patrick

Objet : Peak assymtery not able to fit
Hi,
I am working on a nanocrystalline Nickel sample. I am not able to fit the peaks
to get FWHM and Integral Breadth.
Please see the attached images. Fig. 1 shows the profile and a zoomed view of a
peak. Tail part of the peak is broader.
Fig. 2 shows the winplotr fit. It is not matching the max intensity.
Please give you suggestions to get a better fit for this kind of XRD peak.
Thanks
Apu
