Abstract: Nuclear fusion processes with enhanced rates may be realized by providing energetic electrons in an environment containing a suitable fuel gas, a liquid fuel source, a solid fuel source, a plasma fuel source, or any combination thereof. The fuel source may be deuterium, tritium, a combination thereof, or any fuel source capable of creating deeply screened and/or neutral nuclei when exposed to energetic electrons. Under proper conditions, at least some of the deeply screened and/or neutral nuclei fuse with other nuclei. Neutral versions of deuteron and/or triton nuclei may be created by bringing neutrons with certain energy levels (e.g., around 3 MeV, but optionally less or much less than 3 MeV) into interaction with other neutrons, forming neutral versions of deuterons and/or tritons. Such processes may be used for power generation, heat production, nuclear waste remediation, material creation, and/or medical isotope production, for example.
