Widom–Larsen theory
The Widom-Larsen theory is a theory developed in 2005 by Dr. Allan Widom and Lewis Larsen which describes the production of ultra low momentum neutrons and subsequent catalysis of Low Energy Nuclear Reactions (LENR).[1] Neutrons are hypothesized to be produced during weak interactions when protons capture "heavy" electrons in certain special conditions, such as metallic hydride surfaces.[2] The theory has been criticized as being "based on a number of fallacies and an obscuring way of handling the equations."[3]
The theory was expanded by Dr. Yogendra Srivastava in 2014, and additionally theorized as a possible explanation for neutrons observed in exploding wire experiments, solar corona and flares, as well as to explain neutron production in thunderstorms.[4] However, unreal concentrations of free electrons would be needed for the theory's prediction of neutron yield to be a significant component of thunderstorm neutrons, discounting the theory as an explanation.[5][6][7] The theory has also been suggested as describing the source of neutrons produced in the fracture of piezoelectric and iron-containing rocks.[8][9]
