The spectra of magnetic circular dichroism in the range of the 7 F 6→5 D 4 absorption band and the spectra of magnetic circular polarization of luminescence in the range of the 5 D 4→7 F 5 band in the terbium-gallium garnet Tb3Ga5O12 are studied at a temperature of 80 K. The optical transitions between the Stark sublevels of the 7 F 6, 7 F 5, and 5 D 4 multiplets are identified based on the analysis of the magneto-optical and optical spectra. It is shown that the experimentally determined symmetry and energy of the Stark sublevels of these multiplets confirm the results of numerical calculations of the energy spectrum of the Tb3+ rare-earth ion in terbium-gallium garnet.
