Optically detected magnetic resonance (ODMR) is applied for the first time to the investigation of triplet relaxed excited states (RES) of divalent ns 2 ions in alkali halide crystals. Four types of ODMR spectra related to the RES of Ge 2+ are found. Spectral and angular dependences of ODMR are studied. ODMR data on the RES of monovalent (Ga + ) and divalent (Ge 2+ ) ns 2 ions are discussed. These results provide the first experimental evidence of the effect of nuclear charge on the wavefunction density distribution for excited states of impurity ions in crystals.
