If you can fit via a sum of a broader lorentzian and a narrower one it
may indicate the sample is a "mixture". Are you sure the sample is
microscopically homogenous?

Dear Rietveld users,
I am currently working on Williamson-Hall graph in order to check
strain effect on some new phase.
I have some hyper-lorentzian peaks eta>1 from a pseudo-Voigt
decomposition , then I am not able to get BetaL and BetaG from
Winplotr decomposition.
Does anyone have an idea ?
