Dear Rietvelder's,
Just a small question about Fullprof:
Is it possible to attribute a logical constraining relation between
2 parameters. For instance of the type: Parameter1 + Parameter2 < 1 ?
and how?
Thank you
Edouard.

When I use the pseudo-Voigt function corrected by Thompson-CoX-Hastings
in the Rietveld software the calculations for size and strain are make
with fwhm instead
integral breadth, is this a mistake? or can I calculate the
values for integral breadth and then apply to the formulas for
size/strai
The Integral Breadth (B) value is more suitable for the size-strain analysis
because it is independent of the peak shape. But the FWHMs of a Gaussian and a
Lorentzian peaks with the same B are different.
The relation between IB and FWHM can be derived from the normalization factors
for the Gau

statement made by Stan.
