MessageOne possibility is over-absorption, which will affect the XANES and
EXAFS a bit differently.

Sebastiano:
Sounds like a martensitic transition since it depends on the annealing
time. Thus, as Bruce wrote, XANES and EXAFS may be expected to be
different, due to the different lengths scales - if the boundaries of
local fcc regions are small. Another origin of this discrepancy in x and
y bet

Hi Gemma,
I don't know what that error message from Feff means either, so I am
forwarding this along to the Ifeffit mailing list in hopes that
someone else -- maybe someone from John's group -- can explain.
If I had to guess, I would say that there was a problem constructing
the muffin tins eith
Dear
I study a binary alloy (Fe98.7Cu1.3) where a phase change from bcc to fcc is
evident (at the Cu K edge of course) and it depends on the annealing time. I
have 4 samples A,B,C,D, where the A shows a perfect bcc structure, while the D
a clear fcc structure. B and C have structure that is a
