Cubic paramagnetic centers formed by Yb3+ impurity ions in fluorite-type crystals MeF2 (Me = Cd, Ca, Pb) have been investigated using electron paramagnetic resonance, magnetic circular dichroism, magnetic circular polarization of luminescence, Zeeman splitting of optical absorption and luminescence lines, and optical detection of electron paramagnetic resonance. The g factors of the I-2(7) state in the excited multiplet (2) F (5/2) of Yb3+ ions in Me F-2 crystals, the hyperfine interaction constant (171) A (Yb-171) for the excited multiplet (2) F (5/2) in the CaF2 crystal, and the energies and symmetry properties of all energy levels of Yb3+ ions in MeF2 crystals are determined. The crystal-field parameters for the crystals under investigation are calculated.
