Take at look at this link- http://physics.aps.org/articles/v9/14
The article discusses the discovery of tetraneutrons. A resonance state of 4 neutrons all bound together as a temporarily stable nucleus. When it falls apart the neutrons have very low energy like the neutrons theorized to exist in LENR reactions. That might be the missing piece in the puzzle of why no neutrons are detected during nickel proton LENR and other LENR reactions.
