Аннотация:Within the framework of the quasipotential method in quantum electrodynamics, the correctionsfor the structure of the nucleus are calculated from two-photon exchange diagrams in the hyperfine splittingof energy levels in muon ions of lithium, beryllium and boron. The particle interaction operator is constructedusing the method of projection operators on particle states with certain values of the total atomic momentumF and muon j. Corrections to the structure of the nucleus are presented in integral form containing the electromagneticform factors of the nuclei. After the decomposition of form factors at small momentum transfers,the studied contribution is expressed in terms of the nuclear charge radii. The corrections obtained must betaken into account in the precision calculation of the transition frequencies between the 2S and 2P levels.
