I have no hints about Kalpha3. But some related hint: Several years ago,
we were believing for Kalpha3 or some related satellite lines of the Kalpha
doublet really to disturbe our fundamental parameters lines. In the
beginning of 1999, we found out the so-called "tube-tails" (which better
should be called "focus tails"). For example, have a look at
www.bgmn.de/tubetails.html

This is interesting; I've not seen it (nor have I looked for it).
I have been investigating the "Kalpha3" matter in the course of the certification of SRMs 640c (silicon) and 660a (LaB6) using the FPA code Topas. I'll reporting on this at EPDIC7.
