Hi Alex,
I agree with everything Carlo and Matthew said.
As you say, Li is very light and so the scattering should be weak compared
to Fe. It will also die out much more quickly with "k" than the Fe (or Se)
scattering will. So, if you have enough k-range, simply starting your fit
at higher k
Hi Deltsidis:
Using Artemis, you can compare the calculated Fourier Transforms of the
Se-Fe and Se-Li paths to see if the latter will actually be visible. I
suspect that it will not if it is an impurity phase with small phase
fraction. I would probably start with only Se-Fe and see how well it
If you go beyond first shell, then you'll need to take into account the
Se-Se paths in Li2Se. That may be your best way of detecting Li2Se.

Dear mailing list,
I am currently analyzing some EXAFS data. I am studying a Lix(C5H5N)FeSe
system in a temperature grid that extends from 20 K to 300 K and I have 4
such datasets which correspond to different amount of doping (x). Right
now, im focusing on fitting the 1st coordination cell, in
