Hello Darek,
Thank you so much for your reply.
Yes, i can rely on model, we have performed reitveld refinement to get
the crystallographic data.
To my knowledge, there should not be any other phases.
Your suggestion is quite right. Somehow, i have to constrain my
parameters (to reduce the
Dear Users,
Since long, i was trying to understand the physical meaning of term
Delta E0 and S02 in EXAFS equation. I have little bit of idea about
both of them. for example, S02 is element specific and it is
transferable between samples (if we consider same absorbing atom).
However, I am
Hi Rana,
in the simple approximation E0 can be connected to electronic configuration of
ion, in your situation (but I can only guess) ions can have different E0's (Fe,
Mn), but in the first step I would keep one E0 value for each ion (one E0 for
O, one for Fe, etc), especially that you are
Dear Rana,
Delta E0 is a shift in the Energy origin of k, that is where k=0. For
the experimental data, this was chosen empirically (and so somewhat
arbitrarily) from the measured data. For the FEFF calculation, it was
chosen at the calculated absorption threshold (lowest available
electronic
Hi Rana,
Currently, S02 is usually described as being due to the relaxation of
the other electrons in an atom when a core electron is removed,
resulting in incomplete overlap of initial and final states. This
appears to be a fairly good description, as careful experiments show
good

afraid this is due to some user permission issue in windows 7.
