Fundamental origin of nuclear tuning effects

Abstract

Relations in values of stable nuclear energy intervals and their coincidence with a half of nucleon ∆-excitation and electromagnetic mass splitting of nucleon, pion and leptons are considered as a common tuning effect in nuclear data and particle masses. Combined study of few-nucleon effects in nuclear binding energies and excitations resulted in determination of common parameters for different shells corresponding to residual nucleon interaction and differences in binding energies of nuclei differing by cluster configuration. Stable intervals in energies of nuclear states ranging from hundreds of MeV to tens of keV are considered as a tuning effect in which the QED radiative correction takes part.
