The line shares of the or>tical transition 'Az$"E of Cr" in GdAI0s arecalculated. All the local exchange interactions around the Cr" ion, includingGd"-Gd" ones, are taken into account to determine the eigenstate of the 'A.state and of the 'E state. Possible mechanisms for the transition are consideredand selection rules are obtained for each mechanism. From the comparison of thetheoretical curves with the experiments, the magnitudes of the Cr"-Gd" ex-change integrals are predicted to be - 1.0 cm-' for the',4. state and -0.55 cm-'for the "E state. The agreement between the theory and the experiment is fairlygood.
