Cold fusion/Theory/Widom-Larsen theory

Introduction

Widom-Larsen theory proposes that "heavy electrons" formed at the surface of palladium hydride react with a proton in the palladium nucleus in an inverse beta decay process (e- + p+ -> n + neutrino). The required electron mass enhancement is proposed to be the result of very high electromagnetic fields produced by surface plasmon polariton resonance. The neutron produced would have "ultra low momentum," and thus very high capture cross-section. These neutrons can then cause transmutation and energy release.

Discussion

W-L theory has been heavily promoted by Steve Krivit, of New Energy Times, who has criticized the work that has led most in the field to conclude that the heat/helium balance indicates some kind of deuterium fusion. W-L theory, however, does not account for the isotopic distribution of alleged transmutation products found with cold fusion: Helium predominates (there is no doubt about that, the only question is the exact ratio, which would be dependent on the mix of reactions caused. Isotopic ash other than helium-4, is found only at levels far below that of helium.

Most in the field think that the main reaction, whatever it is, produces only helium and energy, and that other products, such as neutrons, tritium, other transformed elements, and X-rays are the product of secondary reactions or rare branches, or, indeed, some other effect entirely. However, W-L theory still receives some level of positive comment, most notably, recently, from a scientist working in the government who was apparently happy to call his work "not fusion" because of W-L theory. --Abd (discuss • contribs) 14:12, 14 September 2013 (UTC)

W-L alleges that gamma emissions are anisotropic and selective in their directionality. Meaning they, for some mysterious reason, direct themselves toward the heavy electron SPP patches. These transient SPP patches are also imagined to have precisely tuned, energy specific absorptivity capabilities which seems like a stretch as well. Also the persistence of gamma absorption during the "life after death" phase is equally perplexing, as the SPP shields are thought to disappear during this phase. Not to mention delayed gammas caused by neutron absorption also create issues for this heavy electron gamma shield hypothesis.--JohnCMaguire (discuss • contribs) 00:18, 14 October 2013 (UTC)
