Dear Sameh,
I use also 64 bit Win7 and I do not observe any strange behaviour. All
results I got are reasonable, and fitting with different models/starting
parameters gives me the same final results (for the same sample, of
course). More, I can compare results under Win Xp (old computer) with

Ismael,
You do really not need exact parameters which can is helpful in EXAFS. Can
you find any references on the V-C bond length? Since CO is linear, the
V-O and V-C-O scattering should be possible to roughly establish. I think
a number of general inorganic textbooks might have information

Hello All, can someone please help with this:
(1) feff requires that the adsorbing atom be embedded (that is,
surrounded by) other atoms in order to calculate potentials correctly, but
how deeply does the atom need to be embedded?
For example, if I construct a model of an adsorbate on a

Hi winejia,
it is trivial but at the same time hard problem to solve.
There are 2 ways: using Athena and using Artemis
Using Athena you have measured your sample and all possible references.
The result comes from the fit of the linear combination of your references.
Using Artemis is similar but
