NASA - Patent på "Method for Producing Heavy Electrons"

"[0006] Heavy electrons exhibit properties such as unconventional superconductivity, weak antiferromagnetism, and pseudo metamagnetism. More recently, the energy associated with "low energy nuclear reactions" (LENR) has been linked to the production of heavy electrons. Briefly, this theory put forth by Widom and Larsen states that the initiation of LENR activity is due to the coupling of "surface plasmon polaritons" (SPPs) to a proton or deuteron resonance in the lattice of a metal hydride. The theory goes on to describe the production of heavy electron that undergo electron capture by a proton. This activity produces a neutron that is subsequently captured by a nearby atom transmuting it into a new element and releasing positive net energy in the process. See A. Windom et al. "Ultra Low Momentum Neutron Catalyzed Nuclear Reactions on Metallic Hydride Surface," European Physical Journal C-Particles and Fields, 46, pp. 107-112, 2006, and U.S. Pat. No. 7,893,414 issued to Larsen et al. Unfortunately, such heavy electron production has only occurred in small random regions or patches of sample materials/devices. In terms of energy generation or gamma ray shielding, this limits the predictability and effectiveness of the device. Further, random-patch heavy electron production limits the amount of positive net energy that is produced to limit the efficiency of the device in an energy generation application. "

Widom-Larsen:

Om man tillför ett starkt elektriskt fält till vissa metaller, i kontakt med väte, så kan elektronerna börja "grupposcillera" på metallens yta. När det händer så kommer vissa fria elektroner i fältet att få tillräckligt med energi för att kunna slås ihop med en fri proton och bilda en fri neutron. Detta är ett känt fenomen inom elektrosvag (Electroweak) växelverkan, som är ett relativt nytt fält inom fysiken (Nobelpris 1979).
