The luminescence and excitation spectra in the paramagnetic holmium-yttrium gallium garnet Ho0.2Y2.8Ga5O12 (Ho3+:YGG) have been studied experimentally at temperatures T=80 and 293 K. Identification of the radiative 4f -> 4f transitions observed between S-5(2), F-5(4), and I-5(8) multiplets of the ground 4f((10))-configuration of Ho3+ in sites of D-2 symmetry was performed on the base of the results of numerical crystal-field calculations. Analysis of the features observed in the measured magnetic circular dichroism and magnetic circular polarization of luminescence spectra at T=80 K confirms the correctness of the symmetry characterization of the Stark levels for several multiplets of Ho3+ in Ho:YGG. Significant contributions from quasidoublet states in the S-5(2), (5)G(5), and I-5(8) multiplets explain the magnetooptical measurements of the 4f -> 4f transitions under consideration.
