It's definitely a misnomer. I use overabsorption and encourage others to do so. I suppose to track it down would require going back over the seminal papers on the subject. mam On 11/16/2010 10:19 AM, Scott Calvin wrote: Hi all, As some of you know, I'm currently working on a

I tried a few searches, but rapidly get lost in other uses of the term. My guess is we borrowed it from some other spectroscopy, much the way we borrowed Debye-Waller factor from XRD, and then proceeded to change its meaning. But it would be nice to be able to track that down. --Scott

It's a term taken from x-ray fluorescence spectroscopy, or probably really any fluorescence spectroscopy, where it has very sensible meaning: the attenuation of the fluorescence signal by the sample itself. I would even say it is used mostly correctly in XAFS, or at least with a similar intent as

Hi all, I think this comes from the misunderstanding of the effect and the try to explain it as the additional absorption of outgoing light. Am I right? kicaj W dniu 10-11-16 19:19, Scott Calvin pisze: Hi all, As some of you know, I'm currently working on a textbook on XAFS analysis.
