Isotope Effect is the Paradigm of A Non-accelerator Study of the Residual Nuclear Strong Interaction

Artificial activation of the strong interaction by adding of one neutron to the nucleus causes the global reconstruction of the macroscopic characteristics of solids. The experimental evidence of macroscopic manifestation of the strong interaction in optical spectra of solids which are different by term of one neutron from each other (using LiD crystals instead of LiH) has been presented. This evidence is directly seen from luminescence (reflection) and scattering spectra. As far as the gravitation, electromagnetic and weak interactions are the same in both of kind crystals, it only emerges the strong interaction in deuterium nucleus. Therefore a sole conclusion is made that the renormalization of the energy of electromagnetic excitations (electrons, excitons, phonons) is carried out by the strong nuclear interaction. There is a common place in Standard Model of modern physics that the strong nuclear force does not act on leptons. Our experimental results show the violation of this strong conclusion. The necessity to take into account the more close relation between quantum chromodynamics and quantum electrodynamics is underlined. In the first step the quantum electrodynamics should be taken into account the strong interaction at the description of elementary excitations (electrons, excitons, phonons) dynamics in solids. Our experimental results may shed light on a number of fundamental puzzles in modern physics, particularly on the unification of forces.
