Ce(OH)4 is probably not a well-defined compound. I wouldn't use it. I suspect that
"Ce(OH)4" is really hydrated CeO2 nanos. I've measured 30nm CeO2 nanos and
they look like bulk.

I had started with LSQ but switched to peak fitting because I was worried
about the Ce(IV) reference. I have data for bulk CeO2 and Ce(OH)4, but
doesn't this have some Ce(III) impurity in it? I'm not quite sure how to
account for this when I do LSQ.
Another challenge I've had is in using the
Instead of doing a bunch of peak fitting, try LSQ. Use CeO2 (bulk or nanos)
for one reference and some Ce(III) for the other. Consistency check: see that
the Ce(III) fraction is consistent over some set of Ce(III) references.
Ce(III) has an assymetric white line, so it doesn't really fit a
Dear all,
I am trying to extract the % Ce(III) from some CeO2 nanoparticle XAS data. I
have been using moved the peak fitting function in Athena to model the
XANES with an arctan background function and a series of gaussians.
Looking through the literature I haven't seen too many specifics to

Hmm, that seems like some set of packages didn't update completely. What

Dear all,
I was trying to install demeter on my Mac with mac port and the installation
seemed to run smoothly (after following the advice on the installation page!).
However, when I try to start Athena from the command line I get the following

Hi
Is there a possibility to export data, for example the results from the feff
calculation or the fit, whether as binary or as text? At the moment we export
the graph as png image and use a „datathief“ to recover the numerical data.
In this context, I searched for the feff.dat files, but
