Hi:

Does anybody have, or know where to find, L-edge XANES spectra of UO2 and U3O8, that can easily be read into Athena?

I'm asking as there they are not the easiest items to rapidly find.

Oh look! Another example of why we need a good reference spectrum data base! Here: http://leonardo.phys.washington.edu/~ravel/misc/UO2_data.zip is a zip file full of UO2 data taken by the folks in my current research group. This dates from before my time on this job, so I cannot personally vouch for the data. But I examined it and it looks good AND it looks like UO2 ;-) According to the header, it is UO2 powder with SiO2 used a dispersant. The column labeled mcs3 is I0, mcs4 is It. An pin diode and scattered radiation was used for the reference, which is in column mcs5. Hydrated uranyl phosphate is the reference material. I included the project file that I made in the course of checking out the data. You'll probably wish to further play around with the data processing -- I spent all of about 3 minutes at it. I see that there is some U3O8 data on our beamline computer, but I'll have to ask the person who measured it before I swipe it and send it to you. I'll look into that.
