Hello,
I was wondering if the f'' determined by XANES experiment is
quantitatively significant and if it can be contributed by two different
anomalous scatterers.
For example in my protein I know that Co and Zn are present. In theory,
at Zn absorption edge, I have a contribution from Co too. If I perform a
XANES experiment to determine Zn absorption edge and I obtain a f'' of
5.87, does this value correspond to only Zn signal or to a sum of Zn+Co?
Thanks a lot
Matteo
