Dear Rana,

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
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
