I have never used Athena to work up soft x-ray data, but I assume it is
possible. But you run into issues of not having enough pre- or post-edge
data points to do a proper Athena-type normalization. Bruce and co. have
discussed this many times on this list. .
Beside this, fitting your early transition metal soft x-ray data "like
usual K-edge data" would make no sense. There is no EXAFS information in
this energy range (the L_3 and L_2 edges are only separated by 10-15 eV
depending on the edge) and these edges contain strong electron correlation
effects (multiplet effects), not reproduced with FEFF. You need crystal
field codes like deGroot's (http://www.anorg.chem.uu.nl/CTM4XAS/) and this
particular code does not fit your data, only produces a spectrum of X
transition metal in Y oxidation state in Z crystal field environment.
I hope this helps.

Hi,
I am a research student and relatively new to XAFS. I have soft X-Ray L-edge data of Mn and Ni. Is it possible to process this data in Athena and then fit in Artemis like usual K-edge data?
Thanks -- Shoaib
