Luminescence spectra of several rare-earth ions (REI) in the sulfurylchloride-galliumchloride system in the IR and visible spectral ranges are studied. The oscillator strengths of the main electronic transitions of the Eu{sup 3+}, Dy{sup 3+}, and Tm{sup 3+} ions in the absorption spectra in the 5000 - 24000 cm{sup {minus}1} region are calculated at 300 K, and on this basis the spectroscopic intensity parameters {tau}{lambda} in the theory of stimulated electric dipole transitions are estimated. On the basis of the data obtained, the main luminescent parameters of the resonance radiative transitions in Pr{sup 3+}, HO{sup 3+}, Er{sup 3+}, and Yb{sup 3+} ions in the SO{sub 2}Cl{sub 2}-GaCl{sub 3}-LnCl{sub n} systems are calculated. 16 refs., 5 figs., 4 tabs.
