Аннотация:We present far-infrared reflection spectra of Pb0.95Mn0.05Te single crystal doped with gallium between 10 and 300 K. The analysis of the far-infrared reflection spectra was made by a fitting procedure based on the model of coupled oscillators. Together with the strong plasmon-phonon coupling we obtain three local modes of gallium at about 122 cm(-1), 166 cm(-1), and 192 cm(-1). The position of these modes depends on impurity center charge, and their intensity depends on temperature.
