In that paper Schwinger refers to one of his earlier papers. I believe this paper he presented at the first CF conference is based on it:
https://www.lenr-canr.org/acrobat/SchwingerJnuclearene.pdf In it he puts forward a rough mathematical argument (which I don't pretend to understand) as to why he thinks H-D fusion is more likely in a lattice. These two paragraphs grabbed me in particular: <<In the early days of radar, prior to, and at the start of the Second World War, although the British had begun with radio waves that were called high frequency, HF, the need for better resolution led them to VHF, very high frequency, which inexorably brought about VHFI, very high frequency indeed. I mention this ancient history because, in our study of cold fusion, CF, it is useful, and implies no serious loss of relevance, to consider VCFI, very cold fusion indeed. That is, we examine the lattice state at absolute zero. Then there are no phonon excitations — it is the phonon vacuum state — at least initially.>> <<But what is particularly striking is that a change in a parameter by 25% alters the production rate by a factor of ten million, a degree of sensitivity that verges on chaos. In as much as the single parameter Ro/Λ combines, albeit crudely, the effects of all the forces at work within the lattice, the difficulties encountered in reproducing the cold fusion phenomena become more understandable.>> Harry On Thu, Feb 3, 2022 at 11:51 AM Jed Rothwell <jedrothw...@gmail.com> wrote: > The other day Francesco Celani and his friend asked me if I know of any > papers that discuss the role of H in the bulk Pd cold fusion.
