Yes it is mainly down to the Soller slits,
there was a very large thread on
soller slits somewhere in the Rietveld archives
about this discussion. I think the down side of
changing the soller slits is a move away from the
optimum FWHM that can be obtained?
Changing sollers from 0.04 rad to 0.02 or 0.01 reduces the asymmetry,
the FWHM and the intensity, so the peak shape and the resolution become
more optimal but the intensity is sacrificed.
However, the signal to noise ratio becomes better with 0.02/0.01 rad
sollers compared to 0.04 rad
