Holger,
I am not sure how to answer your question, but perhaps this will
help. A pseudo-Voigt is the sum of a Lorentz function and a Gaussian
function and simulates a Voigt, which is their convolution.
There are two ways to parameterize a pseudo-Voigt. One is to have the
same peak widths fo

Hi,
as a new subscriber to the Rietveld mailing list I would like to
introduce
myself. My name is Holger Kohlmann and I am a postdoc in the group of
Prof. Yvon, Institute of Crystallography, University of Geneva,
Switzerland. My research is about the determination of metal hydride

Hi,
New MS-DOS/Win and Linux versions of GSAS have been placed on the LANL ftp
server for GSAS. The principal fix was to deal with powder data sets with
zeros in the profile. Typically this was the last step in the scan because
of a miscount in the number of steps. The latest version of GENLES
Hi,
coming from FullProf and trying a first refinement with GSAS I am a bit
confused about profile functions for CW data. How can I refine the
mixing paramter eta in a pseudo-Voigt function with GSAS?

Dear everyone,
Hi, i am a new user of the Rietveld refinement. Currently my
interest is in the extraction of size/strain information from the line
broadening profile of XRD pattern. The substance i am working on
is organic Paracetamol powder.
I am confused by the concept/definition of the
I recently have tried, for the first time, the fundamental parameters
approach to fitting powder diffraction data using the XFIT program. To the
best of my knowledge I am using a reasonably well aligned system (with a
theta compensating slit in place of a fixed divergence slit), yet when I
