The theoretical study of the process of scattering of high-energy electrons by nuclei makes it possible, using experimental data, to extract sufficiently reliable information about the characteristics of nuclei and about the proton distribution density into them. As is known, the electromagnetic nature of the interaction of electrons with the nucleus greatly simplifies the interpretation of experimental data. In addition, during electron scattering, it is possible to more or less independently vary the energy and momentum of the incident electrons transferred to the nucleus (in contrast to photons), which makes it possible to successfully study the proton density distribution in a wide range of atomic nuclei. To explain this effect, among the multiple assumptions, we again turn to the hypothesis of swelling of the nucleon in the nuclear medium, this time by elastic scattering of electrons. The differential scattering cross sections for electrons with an incident energy of ~ 400 MeV on the nucleus 
and ~ 500 MeV on the nucleus 
are calculated. For the nucleus , the dependence of the density distributions of protons and neutrons is given, taking into account the distribution of charges in them, calculated on the basis of the Hohenberg–Kohn–Sham theory of the quasiparticle nuclear model. Applying the theory of electron scattering on nuclei 
, 
in the distorted-wave approximation for, at an energy of ~ 500 MeV, rather stringent upper limits on the possible increase in the nucleon radius in nuclear matter are established.
