Hi Matthew,
Could it be Pb M5? We've seen that in a few samples. Going above Pb M4
might help verify that or rule it out.

A user on ALS 10.3.2 is taking S K-edge XANES and consistently finding a strong peak at 2484eV (calibration: gypsum white line = 2482.75eV). There's a shoulder at the nominal position of the sulfate peak. Now, peaks below sulfate I can understand, but since there's no such thing as heptavalent sulfur, what could give a peak *above* the sulfate white line? Anybody ever seen that? Yes, we checked calibration. mam _______________________________________________ Ifeffit mailing list Ifeffit@millenia.cars.aps.anl.gov http://millenia.cars.aps.anl.gov/mailman/listinfo/ifeffit
