Just a caveat - CeO2 and Ce(OH)4 have XANES which isn't quite the same
as other Ce4+. There's a shoulder on the low side, as if it were
slightly reduced, and the first peak is at a slightly different
position. Of course, you can use LCF with CeO2 as one of the refs if
you need to.
Dear Neil,
Sorry this may be too exact an interpretation of your English, but if you are
looking at the exafs then calibration is normally pretty irrelevant as long as
it is not wildly out, as you refine E0 anyway in the fitting.
The bond distances will be very little altered by this.
If you
