Andrew, The similarity and contrasts between your work on dense (small) hydrogen and that of several others is truly remarkable. Many brilliant researchers are looking at the shadows on Plato’s cave. A breakthrough is surely imminent.
Other scholarly papers would include those of Mills, Holmlid, Vav’ra, Mayer, Dufour, Lawandy and several more - all of whom have insight and mathematical formality … yet, are different in details and are generally neglected - not given near enough credit by mainstream physics. The common denominator is that hydrogen can become densified and this change radically alters the dynamics of nuclear reactions – some of which may be strongly energetic but not real fusion, after all. There is evidence from Russia/Germany that paired protons collisions - which almost never actually fuse – will nevertheless produce pions – as Holmlid suggests. This is more meaningful in the context of Cerefolini’s “binuclear atom” and provides the easy way to D fusion using the muon, as a decay product of the pion. In the end – Not much fusion yet excess energy due to pion mass being converted into energy. I wish the following paper went a little deeper or there was a followup - “Near-threshold pion production in diproton reactions” by Sergey Dymov for the ANKE collaboration https://iopscience.iop.org/article/10.1088/1742-6596/295/1/012095 Most of the pieces of the puzzle are out there… ---------------- Andrew Meulenberg wrote: Jean-Luc Paillet and I are interested in this 2nd link “A simple argument that small hydrogen may exist” https://www.sciencedirect.com/science/article/pii/S0370269319303624, because we think that 5 (out of 6) sections support our contention that deep-orbit electrons are the theoretical basis for cold fusion…
