“Ab initio calculation of the neutron-proton mass difference” http://arxiv.org/pdf/1406.4088.pdf

A breakthrough in the simulation of subatomic particle processes has just been achieved that accurately predicts the mass of both the proton, the neutron and their mass difference. All the various forces and interactions involved in this balance have been identified and sized.

Before we get into this issue, let us first define some terms. There is a unit of energy called an electron volt (eV), that scientists use when talking about small things like protons, neutrons and electrons. An electron volt is actually a measurement of energy, but scientists can get away with using it to measure mass since mass and energy are related by Einstein’s famous equation, E = mc2. So, in terms of MeV (Megaelectron volts, 1 MeV = 1,000,000 eV), the masses are:

Neutron = 939.56563 MeV
Proton = 938.27231 MeV
Electron = 0.51099906 MeV

“A team based at the University of Wuppertal has now provided the most accurate calculation of the difference in mass between protons and neutrons by combining lattice quantum-chromodynamics and electrodynamics (QCD-QED) modeling to look at the atom’s fundamental building blocks – quarks and gluons. In doing so, the total mass difference was found to be 1.51 ± 0.3MeV. Past QCD-QED studies have been unable to achieve this resolution, yet experimental measurements place the difference at 1.2933322MeV. The researchers argue that the fundamental difference in neutron–proton mass may be down to a competing effect between electromagnetic forces and the mass of quarks.” (“Neutron–proton mass imbalance put on the quantum scales”, Chemistry World, Mar 26 2015 http://www.rsc.org/chemistryworld/2015/03/neutron%E2%80%93proton-mass-imbalance-put-quantum-scales)

The referenced simulation shows that the relationship between the strong force and the electromagnetic force in the makeup of the proton and the neutron is very finely tuned. Even the slightest change would disrupt the way photons and neutrons interact.

The existence and stability of atoms rely on the fact that neutrons are more massive than protons. The measured mass difference is only 0.14% of the average of the two masses. A slightly smaller or larger value would have led to a dramatically different universe. This simulation shows that this difference results from the competition between electromagnetic and mass isospin breaking effects.

This simulation shows that electromagnetism can add mass to the electron and the protons.

For instance, a relative neutron-proton mass difference smaller than about one third of the observed 0.14% or about 400 KeV would cause hydrogen atoms to undergo inverse beta decay, leaving predominantly neutrons.

It has become clear that a relative neutron-proton mass difference close to 0.14% is needed to explain the universe as we observe it today. As we show here, this tiny mass splitting is the result of a subtle cancellation between electromagnetic and quark mass difference effects.

This simulation shows how electromagnetism affects the tiny isospin splittings which are the subject of the present paper hereto referenced.

Also show here is how neutron-proton mass splitting is a function of quark-mass difference and electromagnetic coupling.

Now the level of electromagnetic energy needed to tip the very delicate balance between the masses of the proton and neutron is of the order of about 1 MeV or less. If a process in LENR can add electromagnetic energy to the proton and neutron pair, the interactions between the proton and the neutron would be disrupted.

For example, in the Lugano E-Cat Test report, light isotopes of nickel (NI58) were transmuted to heaver isotopes (NI62) but quizzically no free neutrons were detected. The irradiation of an absorbed proton by a reasonably modest level of EMF(400 KeV) would transform a proton into a neutron as shown by this simulation.
