Excitation of Atoms and Broadening of Spectral Lines [Paperback]

A survey of elementary processes and mechanisms, presenting useful and relatively simple methods of approximation for calculating the effective cross sections, giving a number of approximate formulas. Extensive tables list cross sections and rate coefficients for various atoms and elementary processes. For this second edition several sections and formulas have been substantially revised, the tables recalculated using the updated version of ATOM and recent progress in the field has been added.Excitation of Atoms and Broadening of Spectral Lines povides a survey of elementary processes and mechanisms.
