The dependence of the line shapes on the excitation energy in the Ramanscattering (RS) of EuTe at low temperatures is theoretically studied, and isinterpreted in terms of the modulation of 5d spin-orbit interaction by latticedisplacement. A sharp line induced by the staggered magnetuzatuon appears 111the vicinity of the absorption edge. This line is observed in off-diagonal Ramanpolarization configuration. For the incident light with energy near the middle ofthe exciton absorption, the sharp line disappears and broad line assisted by themagnon excitation appears in both off-diagonal and diagonal polarization con-figurations. These calculated results are consistent with the experimetntal result.The RS spectra under a weak magnetic field are also calculated.
