Modern View of the Origin of Isotope Effect

This book describes of the direct observation of the macroscopic manifestation of residual strong nuclear interaction via elementary excitations in solids which are different by term of one neutron from each other. The experimental evidence is directly seen from luminescence and light scattering spectra. As far as the gravitation electromagnetic and weak interactions are the same in both kind (LiD and LiH ¹²C and ¹³C) crystals it only changes the strong interactions therefore a logical conclusion is made that the renormalization of the energy of electromagnetic excitations (excitons phonons) is carried out by the strong nuclear interaction. The last one simultaneously indicates the origin of the isotope effect is caused by the strong interaction. The mediator between neutron and lepton in strong interaction may be X – boson or some others who have long – range interaction. This discovery opens a new avenue in particles and nuclear physics.
