Can someone explain in simple terms "K mixing level" and "K selectivity" in nuclear decay processes ? ...as it relates to the "K quantum number".
And does it relate directly to the nuclear angular momentum?...and selection rules? How so? Dumb it down for me please. Thank you kindly.

For a nonspherical nucleus, K is the projection of total angular momentum on the body axis. A Kmixing level is a state which is a superposition of wavefunctions with different values of K. Here's a paper which describes it.

Can you please explain exactly what the author is getting at in the first 3 paragraphs. Is he saying the selection rules prevent EM decay due to high total orbital nuclear angular momentum as compared to change in total A. M. of transition,... (and also since such is the case in which transitional change in K being so much smaller than L ).?? Please explain in detail if you can. Is the isomer metastable due to the smallness of delta J or delta K ? Thanks. ...
