I am unsure how knowledgeable you are about Wyttenbach's current work.
If Wyttenbach is currently seeing gamma radiation from fuel not prepared by Russ George (but prepared generally according to George's ideas) then this is a sort of replication of George's previous results isn't it? I would think that would be important.
Don't think too hard. As for being unsure (your favourite stance) you will see a paper published by Jurg and me later this years or early 2022. So you might say we collaborate.
