To increase sensitivity to partial/mixed occupation and also solve the case of
3 or more atoms in the same site (you have an infinite number of solutions that
give you the same scattering factor, both x-ray and neutrons) we are developing
a combined XRD-XRF analysis. Some preliminary

Dear Othman,
I agree with previous comments and warnings from colleagues.
But regarding your specific question, you need to check the manuals for
GSAS II or FULLPROF on how to setup the constraints on the site occupancies
of all the atoms and sites involved.
It is not sufficient to constrain
