How to measure MG lines?
« on: July 03, 2014, 06:46:59 AM »
Hi John,

I would like to measure some MG lines. However, if I put U Mg or similar, the software complains that MG is not a valid x-ray line. I disagree and say that MG is a valid X-ray line.

How would I do that?

Now I am measuring U La IV (and just set the peak position to MG), that works, but is more like a workaround...

Cheers
Philipp

Let's just say that the MG line is "not supported".   Supported lines are Ka, Kb, La, Lb, Ma and Mb.

Why is the MG emission line not supported for quantification?  Well because we currently can't even do decent physics for beta lines much less these MG lines!

Ok, fair enough. I will go for the U La IV workaround then. That is only about 2000 Cameca spectro units away from the MG, and PfE does not complain... :-) It only warns for a far away peak offset.
