Hi All
I am having problems in comparing the real bond length as obtained from EXAFS
data and Reitveld analysis of XRD data of te same sample. The bond lengths as
observed from the XAFS data seems to be much smaller that that from XRD. Is
there some multiplication factor known in literature to
Hello all,
After calibration, alignment and merging V K edge data, there seems to
be a large peak in R space below 1 A. From most examples and readings,
this would seem to be noise since atoms do not reside that close to each
other. Adding a background addresses this noise but then the
Hi Chris:
If you could attach an Athena project file, it would help us to answer
your question.

Chris,
You'll answer this question when you post a project file; but since you
mention the pre-edge feature, have you reset the Eo to approx. halfway up
the absorption edge instead of on the pre-edge feature itself?

Hi Chris:
I have taken a look at your project file and, indeed, the edge setting is
more or less correct. In this case, the intensity below 1A is certainly
background and you can see this by plotting the data in R-space with
k-weight of 2 or 3 and then slowly increase the Rbkg (I find that
