It's long been the case that Artemis / Atoms can generate an input file for
Feff8, even though Feff8 is not distrubuted with Demeter.  There have been
several discussions on this list over the past several years about how to
use a version of Feff other than feff6l included in the distribution.

If you have a working Feff8 executable, Artemis should be able to use it.
But, I am not aware of a distribution of feff85L.exe for Windows.  Bruce
and I have been working on Feff85L for EXAFS, but there is not a single
Windows executable in that work.  Maybe someone else has produced such a

Artemis has been able to use various versions of Feff8 for a very long
time.  It does not come with a version of Feff8, at least not yet.

Feff9 is the latest version of Feff.  Isn't it awesome that the Feff tab
gives you a link to the Feff documention?

Well, it's not exactly true that one can now only wish that Demeter allow
use of Feff8.  One can also work on it. These are open source projects,
desparate for help, including things as simple as encouragement, testing,
and giving complete and actionable error reports. If you expect someone
else to give you a free, pre-packaged solution that works for you without
effort, you might be waiting a very long time.
