A Top-down approach to Fundamental Interactions, viXra:1307.0082 [2] presents the author’s attempt to understand if there is an information code underlying nature. Once the energy components were understood, a model for the neutron and proton was developed. The proton model is presented in Reference 2 and repeated below under the next heading. The proton model shows that there is a 10.15 MeV orbit that losses energy and is responsible for the binding energy curve. The goals of this paper are to verify the value 10.15 MeV and present a simple model of atomic binding energy. Literature cites “water drop” models for binding energy that are admittedly empirical. Quantum physicists have suggested that there should be “electron like” shells inside atoms but to the author’s knowledge they remain unclear. If there are shells the nucleons should fall into lower energy states releasing the remainder as binding energy. The author explored this possibility. Empirically, the model was successful but no explanation could be found for why a nucleon occupied a given shell. The first part of the binding energy curve rises quickly and then levels off as saturation occurs. When the author compared the shape of the curve to a probability based model a simple relationship was discovered. The relationship is almost identical to the fundamentals presented in reference 2.
