This monograph certralizes the studies of a "perturbed atom" that is an atom under the influence of different perturbations in plasmas. Atoms and Plasmas covers the fundamental aspects of modern physics, such as Plasma radiation, Atomic collisions, Spectral line broadening, Laser spectroscopy, etc. and should be interesting for scientists as well as for newcomers in this field.
