Abstract
The optical absorption spectra of high-density (10(16)-10(19) cm(-3)) sodiu m vapors were studied in a broad spectral range (0.35-1.1 mu m). The intens ity of thermal radiation from sodium vapors was measured in the 2-3 mu m wa velength interval. It is established that the effect of metal clusters can account neither for the observed structure of absorption spectra nor for th e increased intensity of emission in the near-IR range reported in some wor ks (in particular, for the emission spectra of high-pressure gas-discharge sodium lamps).
