Abstract:An analysis has been made of experimental data on level spectra, single-nucleon transfer reactions near closed shells, and data on the polarization effects in charge-exchange (p, n) reactions between isoanalog states of nuclei with even A. The analysis has allowed us to conclude that there is a significant difference between the spin-orbit splittings of neutrons and protons in identical orbitals. This conclusion is confirmed in a framework of different theoretical approaches.
