Beschreibung:
Radio Recombination Lines is a comprehensive guide to the physics and observations of Radio Recombination Lines from astronomical sources. It includes the history of RRL detections, the astrophysics underlying their intensities and line shapes including topics like departures from LTE and Stark broadening, the maximum possible size of an atom, as well as detailed descriptions of the astronomical topics for which RRLs have proved to be effective tools. In addition, the appendix includes detailed physics underlying the Bohr atomic model, tables of RRL frequencies including fine structure components, techniques for calculating hydrogenic oscillator strengths, and formulas for converting telescope intensity units to astrophysical ones.
