The explanation of the origin of inelastic peaks in magnetic neutron scattering spectra of the mixed-valent semiconductor SmB6 is proposed. It is shown that the excitonic theory of the intermediate valence state not only gives the value of the peak frequency but also explains the unusual angular dependence of the intensity of inelastic magnetic scattering and describes the dispersion of magnetic excitations in good agreement with experiment.
