Lack of expected reaction products
Conventional deuteron fusion is a two-step process, in which an unstable high energy intermediary is formed:
D + D → 4He * + 24 MeV
Experiments have observed only three decay pathways for this excited-state nucleus, with the branching ratio showing the probability that any given intermediate follows a particular pathway. The products formed via these decay pathways are:
4He* → n + 3He + 3.3 MeV (ratio=50%)
4He* → p + 3H + 4.0 MeV (ratio=50%)
4He* → 4He + γ + 24 MeV (ratio=10−6)
Only about one in one million of the intermediaries decay along the third pathway, making its products comparatively rare when compared to the other paths. This result is consistent with the predictions of the Bohr model. If one watt ( 1 eV = 1.602 x 10−19 joule) of nuclear power were produced from deuteron fusion consistent with known branching ratios, the resulting neutron and tritium (3H) production would be easily measured. Some researchers reported detecting 4He but without the expected neutron or tritium production; such a result would require branching ratios strongly favouring the third pathway, with the actual rates of the first two pathways lower by at least five orders of magnitude than observations from other experiments, directly contradicting both theoretically predicted and observed branching probabilities. Those reports of 4He production did not include detection of gamma rays, which would require the third pathway to have been changed somehow so that gamma rays are no longer emitted.
The known rate of the decay process together with the inter-atomic spacing in a metallic crystal makes heat transfer of the 24 MeV excess energy into the host metal lattice prior to the intermediary's decay inexplicable in terms of conventional understandings of momentum and energy transfer, and even then we would see measurable levels of radiations. Also, experiments indicate that the ratios of deuterium fusion remain constant at different energies. In general, pressure and chemical environment only cause small changes to fusion ratios. An early explanation invoked the Oppenheimer–Phillips process at low energies, but its magnitude was too small to explain the altered ratios.

Umstrittene Nickel-Wasserstoff-Reaktion "eCat"
Anfang 2011 behauptete der italienische Unternehmer Andrea Rossi zusammen mit dem Physiker Sergio Focardi, dass er Nickel und Wasserstoff zu Kupfer verschmelzen und damit eine sich über längere Zeit selbst aufrechterhaltende exotherme Reaktion erzeugen könne.[31][32] Allen 15 Ansprüchen eines Patentantrags vom 2008 wurden vom Europäischen Patentamt in einem Prüfbericht 2010 die Eigenschaft einer Erfindung (inventive step) abgesprochen.[33][34] Unabhängige Bestätigungen des Experiments liegen bisher nicht vor. Die bei solchen Fusionsreaktionen eigentlich zu erwartende Gammastrahlung wurde nicht beobachtet. Die für den Herbst 2011 in Griechenland angekündigte Präsentation eines funktionsfähigen Reaktors wurde abgesagt.[35] Eine gründliche Untersuchung des Geräts erlaubt Rossi nicht. Mehrere Gutachter sahen daher von einer abschließenden Beurteilung ab.[36] Der LENR-Blogger K
