对于杂质中心，利用电子跃迁中活跃的一个局域或赝局域模模型，并考虑了该模的平衡位置和频率的变化，研究了低温下由发光、拉曼散射、热发光和干涉项组成的共振二次辐射谱。结果表明，后者在共振拉曼散射和热发光的分类问题中起着至关重要的作用。详细分析了三种情况下的光谱反斯托克斯区：单色激发、“白”激发和中间激发。考虑了不同弛豫通道的干涉对谱线强度、宽度和形状的影响。

For an impurity centre the resonant secondary radiation spectrum, consisting of luminescence, Raman scattering, hot luminescence, and interference terms, is studied at low temperatures using the model of one local or pseudolocal mode, active in the electronic transition and taking into account the change of the equilibrium position and frequency of this mode. It is shown that the latter plays an essential role in the problem of the classification of the resonant Raman scattering and hot luminescence. The anti-Stokes region of the spectrum is analysed in detail for three cases of excitation: monochromatic, “white”, and intermediate excitation. The influence of the interference of different relaxation channels on the intensity, width, and shape of the lines is considered.
