Recombination lines at radio wavelengths have been - and still are
- a p- erful tool for modern astronomy. For more than 30years, they
have allowed astronomers to probe the gases from which stars form.
They have even been detected in the Sun. In addition, observations
of these spectral lines facilitate basic research into the atom, in
forms and environments that can only exist in the huge dimensions
and extreme conditions of cosmic laboratories. We intend this book
to serve as a tourist's guide to the world of Radio Recombination
Lines. It contains three divisions: a history of their discovery,
the physics of how they form and how their voyage to us in?uences
their spectral pro?les, and a description of their many
astronomical contributions
todate.Theappendixincludessupplementarycalculationsthatmaybeuseful
to some astronomers. This material also includes tables of line
frequencies from 12MHz to 30THz (?=10?m) as well as FORTRAN
computer code to calculate the ?ne-structure components of the
lines, to evaluate radial matrix integrals, and to calculate the
departure coe?cients of hydrogen in a cosmic environment. It also
describes how to convert observational to astrophysical units.The
