[Ifeffit] Cadmium K-edge

Hi all,

I processed my XAS data and compare them with standards from Farrel Lytle
Database. (http://img717.imageshack.us/i/xasw.jpg/).

In the RSF, both sample 1 and 2 has a major peak at R = ca. 1.8 A. sample 1
has an additional peak at R = ca. 2.3 A. I wonder if this tiny peak is
significant.

It seems both samples has peak positions similar to those of CdO standard,
which sound logical because the cadmium will bind to the surface oxygen of
the material.

I looking at fitting sample 1 and 2 using whatever crystallographic info of
CdO I can get my hands on.

Wonder if the plan make sense.

Happy new year,
Alan
