Abstract: 
In this report, the observations of radio recombination lines which are carried out with radio telescope UTR-2 using a 4096-channel autocorrelometer and 16-bit digital spectral analyzer are described. The correct processing and interpretation of observational results provide new information about the basic parameters of the interstellar medium – electron temperature, electron density, element abundances, distribution of ionized gas. Analysis of radio recombination lines’ parameters provides new opportunities not only for astrophysics but also for physical science as a whole.
Keywords: quantum transitions, radio recombination lines, radio telescope UTR-2, spectral analyzer
