描述Since their first detection 15 years ago, radio recombination lines from several elements have been observed in a wide variety of objects including HII regions, planetary nebulae, molecular clouds, the diffuse interstellar medium, and recently, other galaxies. The observations span almost the entire range from 0.1 to 100 GHz, and employ both single­ djsh and aperture synthesis techniques. The theory of radio recombination lines has also advanced strongly, to the point where it is perhaps one of the best-understood in astro­ physics. In a parallel development, it has become possible over the last decade to study these same highly-excited atoms in the laboratory; this work provides further confirmation of the theoretical framework. However there has been continuing controversy over the astrophysical interpre­ tation of radio recombination line observations, especially regarding the role of stimulated emission. A workshop was held in Ottawa on 24-25 August, 1979, bringing together many of the active scientists to review the field and discuss these questions of interpretation. A broad concensus has emerged: the subtleties of the line-formation process are understood, and the conditions

Systematic Variation of the Helium Ionization in Galactic HII Regionse for larger radii. This behavior can be interpreted as reflecting a general decrease of the He abundance with the galactic radius (similar to that also found for planetary nebulae; Torres-Peimbert and Peimbert, 1977) plus a reduction of the ionization in the inner parts of the Galaxy. The crucial aspect is that the observations

Carbon Radio Recombination Line Emission from Dark Clouds source and as an extended source of far infrared thermal dust emission; the CII region coincides with a localized region of enhanced molecular line emission. We summarize the physical properties (temperature and density) of the CII regions as derived from the recombination line observations and comment on prospects for further research.

Interpretation of HII Region Radio Recombination Linesno need for another review in the traditional sense. There does however seem to be a certain amount of confusion, at least among observers, as to whether or not theory and observations are consistent with one another. One problem is that simple models of the recombination line transfer do not appear

Radio Recombination Lines from Planetary Nebulaen (Terzian 1973, 1978). Only in recent years it has been possible to detect these lines with adequate signal-to-noise ratios. The largest radio telescopes have been used for such observations with long integration times. Successful results have been obtained for Hnα lines with n ≤ 110, and only uppe
