In a wide range of temperature and doping level the small signal lifetime for Auger recombination, spontaneous emission of radiation, and for spontaneous emission of plasmons is calculated in the compounds Pb 0.78 Sno. 22 Te and Pb 0.91 Sno 0.09 Se. In the calculation degeneracy of the carrier gas and anisotropy of band structure is taken into account. At donor concentrations N D > 10 19 cm −3 , recombination by emission of plasmons dominates. For N D < 5 ×10 16 cm −3 radiative recombination dominates in Pb 0.78 . Sno 22 Se up to temperatures T L < 180 K, in Pb 0.09 Se, however, up to 230 K.
