Thanks @JohnyFive for the replies.
It could be that the relative background could be interesting even if it is a bit contaminated. Actually maybe even more relevant in some ways.
But I can also understand if you may also be concerned about using that if it relates to other experiments you are running that you prefer to keep close at this time.
Could be interesting to do your self if you haven’t already . Just in case it gives some clues.
It’s Interesting that you used LiOD... I wish I had more time to keep up with things. I miss some details like this sometimes even though it’s clearly stated. My Apologies for that.
Lithium is interesting if it produces two 3.4 MeV alpha. Some times the broad spectrum aspect of these kinds of plots seem to me to look like they correspond to a Q value not far off this. But how that would correspond to the half-life behavior you see on the paper when you remove it.... I have no idea.
Given your thoughts about gamma... It does seem it could imply beta or alpha are generated in and from the paper. It would be strange for Be8 to continue to be captured or generated there in the paper after the paper is removed though... I suppose activation of carbon etc by bomardment would have similar constraints...
It’s a good experiment for its simplicity and the questions it raises..
I’m enjoying following when I can. Good luck with It.
