C 105, L041302 (2022) Single-nucleon energies changing with nucleon number NUCLEAR STRUCTURE A=16-208; analyzed available data on neutron and proton single-particle energies for 33 different orbitals in even-even nuclei. Discussed the dependence of energy of states depending on the number of neutrons and protons. Pointed out that change in energy of neutron states with neutron number or proton states with protons number is approximately a factor of four weaker in magnitude.
