Another possibility. to clarify the possible relevance of neuglu in the LENR system, for those who believe that real 4He is found in the ash is that helium derives from a two-step process. The reaction does not produce gamma radiation since the mass-deficit has actually been used up in the process of removing (borrowing) the neuglu from the host.
In the first stage, which happens in the metal matrix, neuglu binds together two neutrons of two separated deuterons, which are then further compressed into 4He due to fluctuations in the internal pressurization of the metal matrix. Since the neuglu is lost to the host metal (e.g. palladium) its mass energy is deducted. This works out pretty well since the mass deficit of helium following deuterium fusion is 24 MeV and the mass-energy equivalent for neuglu is estimated to be about 15-17 MeV. This pressurization energy of the second stage would balance the books without a gamma. That complication is admittedly nothing more than a rationalization for now. but it is quite elegant in its own way.
