LENR theory responsible for the elemental composition of the Earth's crust

A type of low-energy nuclear reaction, ignored by nuclear physics, responsible for the difference in the elemental compositions of the Earth's crust and the interstellar material from which the crust formed is investigated. The existing difference is predicted to arise from interactions between two identical nuclides at a distance, during which energy is exchanged, resulting in the transfer of some nucleons from one nuclide to the other. Specific reactions responsible for these differences and the physical processes facilitating such transfers are described. The requirements and necessary conditions for such reactions are theoretically determined. Examples are given where these requirements are met.
