Marks valued comment, I'm not an expert on EELS. Sorry, the
theoretical part of what I said before is not correct. In WIEN2k,
you should be able to calculate the ELNES parts of the EELS
spectrum. See the description of case.innes in the Telnes3
section of the WIEN2k usersguide. Rather than having to
'identify' the element (atom), it looks like you have to 'specify'
what the inequivalent atom is and what the energy-loss of the 1st
edge should be. If I now understand your question correctly, you
are asking about how to identify and understand the peaks in ELNES
spectra. I don't know in detail, but I think that is done using
an overlap population diagram. You should be able to read more
about it in the document and references contained therein at:<br>

<br>
Also, you might what to have a look at the WIEN2k ELNES documents
on the WIEN2k website [ <a class="moz-txt-link-freetext" href="http://www.wien2k.at/reg_user/textbooks/">http://www.wien2k.at/reg_user/textbooks/</a>

However, I don't know if you can import WIEN2k EELS
data into them, and<br>
I'm not aware of any software for theoretical EELS
data.<br>
<br>
So you might have to do the edge identification by
hand. There is a<br>
book titled "Analytical Electron Microscopy for
Materials Science" by<br>
Daisuke Shindo and Tetsuo Oikawa, which you should be
able to find on<br>
the Springer website at<br>

<br>
In the Front Matter pdf, there is a "Table of Electron
Binding Energies<br>
(eV) for Electron Energy-Loss Spectra (EELS)", and it
says, "This table<br>
can be used to identify edges in energy-loss spectra".<br>
