Thanks to a link posted by new member "ele" in another thread, I found a potentially important paper, just published by Russian nuclear theorist Yuri Ratis.
I have taken the liberty of posting a rough English translation of the pdf, at https://goo.gl/Z3e5nZ
Among the startling conclusions:
5. Neutrons is a boson, ie, has a spin
13. The weak interaction can lead to a temporary neutralization of the charge of the proton,
and thus catalyze nuclear reactions at low energies.
It's a lengthy paper, needing close study to understand in detail. Hopefully some of the more math-enabled readers here will find it interesting enough to comment further.
