Abstract: Using a photoacoustic spectrometer model GS-1 we have obtained the solid state photoacoustic spectra of 14 rare earth oxides (except the one for radioactive promethium). These spectra are in good agreement with cor-responding diffusion reflectance spectra, but the photoacoustic measurement is simpler.
