So the basic understanding I have of electron transitions for EDX, XES and other x-ray fluorescence techniques is that a transition from:(adsbygoogle = window.adsbygoogle || []).push({});

L to K shell is named [itex]K\alpha[/itex]

M to K shell is [itex]K\beta[/itex]

N to K shell is [itex]K\gamma[/itex]

M to L shell is [itex]K\alpha[/itex]

etc.

Grand, easy... google leads me to multiple diagrams explaining it like this. But now I have a feeling that's a bit woolly and the real story is more convoluted. The http://xdb.lbl.gov/Section1/Sec_1-2.html" [Broken] which shows [itex]L\beta _{2}[/itex] being an N to L transition and [itex]K\beta _{2}[/itex] being an N to K transition...

Can anyone explain to me why this is? Is there a physical logic to it or is it just from historical labeling of lines observed?

Also the last number, say [itex]L\beta _{2}[/itex], what does the 2 refer to? Is it the intensity of the line? The energy position?

Cheers
