Description
Summary:Artificial activation of the strong interaction by adding 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 the optical spectra of solids which differ by one neutron from each other (using LiD crystals instead LiH ones) is presented for the first time. As far as the electromagnetic and weak interactions are the same in both kind of crystals, it only changes the strong interaction, therefore the renormalization of the energy of electromagnetic excitations (electrons, excitons, phonons) is carried out by the strong nuclear interaction. The necessity to take into account some new residual inter-relations between strong and electromagnetic interactions are underlined. An interpretation of the isotopic shift caused by the addition of one neutron is also discussed. From the experimental value of the isotopic shift we obtain a residual strong coupling constant equal to 2.4680.
