Raman spectra at different temperatures are reported for K3Ba3C60.A systematic change of the Raman spectra with temperature is observed.The development of the linewidth and intensity for all modes with temperature is in sharp contrast to the case for pure C60.An anomalously large up-shift of 9 cm-1 between 20 K and room temperature for the pinch Ag(2) mode suggests the existence of hybridization between the C60 molecules and the intercalants.The relative intensity of the doublet of Ag(1) systemtically changes with decreasing temperature.
