The existence of hypernuclei was discovered in a middle of the last century. During the formation of these nuclei under the action of cosmic rays, one of the nucleons passes into its excited state and turns into the \(\Lambda\)- or \(\Sigma\)-particle. In this paper, it is shown that various combinations and excited states of stable elementary particles have masses and magnetic moments, the values of which coincide with the masses and magnetic moments of shortlived particles with satisfactory accuracy. Based on this agreement, it is assumed that unstable elementary particles can be excited states of various combinations of electrons, positrons and protons, and not quarks with fractional charges, as is usually assumed at present.
