In spectral studies, a DDS-30 lamp with a deuterium-neon filling is often used as a source, which gives a continuous emission spectrum in the violet and ultraviolet range. Using the MDR-206 monochromator, plasma emission spectra were recorded and it was shown that in the wavelength range 300...450 nm a high intensity of continuous radiation is observed. A study of the radiation characteristics of the lamp was carried out, the plasma parameters have been experimentally determined, and the excess of the power registered in this region over the calculated radiation associated with recombination radiation has been shown. The observed anomaly may be associated, apparently, with the transfer of excitation from neon atoms to deuterium molecules.
