[Ifeffit] Peaks in MCA spectra

2014-03-31 Thread George Sterbinsky
Hello, I am writing with a general XAS question. It does not necessarily pertain to Ifeffit, however, I think the topic is something some, maybe most, list members will be knowledgeable about. So it seems like this list is a good place to post this question. On to the question. I have attached a

Hmmm. An interesting brain-teaser. Scaling very roughly from the graph, the mystery peak shows up at about 715eV. This is consistent with Fe. Could there be a background from Fe somewhere in the detection systen? The intensity between the O and Co peaks doesn't really look like a peak, but

Hi George, Calibrated spectra would help, but if we guess the calibration is 0.56 bins/ eV, then we'd have line E (eV) bin # - Co La1,2 775 434 O Ka1,2 525 294 C Ka1,2 277 155 which
