Scientific paper

Carbon recombination lines have been detected in absorption at decameter wavelengths in the direction of the DR-21 and S140 nebulae, which indicates the presence of a fairly extensive cold partially ionized interstellar medium with an electron density of less than 1/cu cm. Some differences between models of regions responsible for very low-frequency and very high-frequency carbon lines are confirmed. The method proposed for estimating the size of the regions makes it possible to obtain useful information practically from the single fact of detecting decameter recombination absorption lines.
