Re: Modelling of peak shape for fixed wavelength

[Patrick Weisbecker]

Hello,

About influence of misalignement on peak assymetry; A good mean to improve
symetry of peaks at low angles is to use soller slits, indeed other
parameters than alignement can be responsible for asymetry.

As for modeling peak shape, I use Fullprof and i also have difficulties to
find a good agreement between experimental and calculated pattern because
of asymetry at low angles. 
If someone knows if a particular profile (on this sofware) is best suited
for asymetry i will appreciate.
