axil: This one you posted a year ago: I had (at that time ..) a short communication with Shafeev about his follow-up Transmutation paper, where he made the same wrong claims, because he did not measure the spectrum very accurately. The problem is that the most important gamma line (352keV) of Pb214 is just missing, what invalidates the findings.
You should ask him whether he now has a more accurate measurement! The only value of this paper is: Something interesting is going on -- but we don't know what!
