I am glad to see a discussion of changes in mass depending on environment. I feel that this is fundamental to the CF story of D-D => 4He and many other observables.
Rest mass (stationary, isolated in space, and with zero potentials) is constant. Add velocity and the effective mass increases. Add fields/potentials, and the effective mass (not the rest mass) increases or decreases. Adding an electron to a proton orbit decreases the atomic mass to below the combined rest masses of a proton and electron. The electron effective mass increases from its increase in velocity. The remaining atomic mass (that of the proton) must decrease as a photon is released. The Klein-Gordon and Dirac equations predict deep electron orbits with binding energy of > 0.5 MeV. The resulting femto-atom will have that much less mass. The femto-hydrogen electron will be relativistic (~ 1 or ~100 MeV depending on the model used). The nucleus (a proton) mass must be reduced by at least that amount. In either model, the atomic mass changes by the same amount (~ 0.5 MeV). This change in nuclear mass has a major impact on how we calculate things and claim what is possible or not in this new regime. The basis for the nuclear change comes from the nucleon interactions in a compound nucleus and in the quark interactions in even a single proton. These charged components are greatly affected by the strong fields of a proximate (fermi distance of a) deep-orbit electron. Andrew M.
