DISTORTIONS OF THE COSMIC BLACKBODY SPECTRUM DUE TO LUMINESCENCE OF H2D+ MOLECULES

The shapes of spectral features that can take place in the Rayleigh-Je ans region of the microwave background spectrum are calculated. These distortions are produced at z = 10-30 by H2D+ molecules that are absor bing the non-equilibrium photons of the primordial distortions of CMBR spectrum in the Wien region (connected with the energy release in the early Universe) and that are emitting photons in wavelength region la mbda = 1-100 mm. It is shown that with reasonable values of the initia l distortions spectral features emerge that can have sufficiently larg e amplitudes to be detectable.
