FOSSIL RADIO LINES OF HYDROGEN IN THE COSMIC BACKGROUND-RADIATION AT DECIMETER AND METER WAVELENGTHS

The formation of spectral disturbances of Cosmic Background Radiation (CBR) by hydrogen recombination at redshift z = 1500 is considered. Sp ecial attention is paid here to the decimeter and meter wavelength ban ds. The most distinctive properties of spectral disturbances are an in crease in amplitude with wavelength, followed by a decrease intensity of CBR and an increasing asymmetry of the contours of separate lines. It is shown, that it might be possible from their observations to dete rmine the average density of barion and the average total density of m atter in the Universe with great accuracy.
